What is the GAH SR200 refrigeration system?

The GAH SR200 refrigeration system is a cabin-mounted, closed-cycle cooling assembly designed to maintain stable, programmable temperatures in commercial van cargo areas. Utilising compressor-driven heat exchange, the system stabilises internal environments in both chilled (typically 0°C to +8°C) and frozen (-20°C and below) ranges. Core to its operation is a digitally managed controller that allows operators to programme and monitor temperature setpoints, conduct real-time diagnostics, and automate alerts in response to deviation or fault.

Comprising high-efficiency compressors, sealed evaporators, and corrosion-resistant condensers, the SR200 balances thermal recovery performance with energy consumption considerations. The versatility of the platform supports single- or dual-zone configuration, enabling logistics companies to service clients requiring multi-temperature transport within a single asset. GAH Refrigeration Ltd’s commitment to research and development—combined with partnerships with leading converters—yields ongoing enhancements in refrigerant efficiency, environmental impact, and compliance adaptability.

How was the unit developed?

Development of the SR200 system emerged from an industry-wide push to modernise and standardise refrigerated van applications at the intersection of tightening regulatory standards and shifting logistics models. Early refrigerated vans, often relying on retrofitted passive or single-zone systems, offered limited flexibility in supporting urban, multi-drop, and compliance-heavy delivery models. By the late 2000s, advances in mechanical engineering and digital monitoring led to a new generation of electrically integrated refrigeration units capable of rapid pull-down and variable control.

GAH Refrigeration’s engineering teams iterated on modular compressor technology, integrating environmentally sustainable refrigerants and supporting the transition to hybrid and electric van chassis—a reflection of both regulatory and client-driven sustainability goals. Innovations such as programmable digital controllers, plug-and-play electric standby units, and remote diagnostic ports followed, establishing the SR200 as a platform of choice where product integrity and audit-readiness became central concerns. Collaboration with conversion specialists, especially Glacier Vehicles, refined both instal protocols and aftersales support, accelerating the system’s acceptance in food, pharmaceutical, and multi-sector supply chains.

What are the main technical specifications?

The technical architecture of the SR200 prioritises thermal performance, energy flexibility, and compliance with evolving refrigerant guidelines. At its core, the system operates via a compressor-condenser-evaporator loop with precision thermostatic and digital logging controls.

Parameter	Specification
Cooling output	~2000W (variable, model-specific)
Cargo temperature	0°C to +8°C (chill), –20°C (freeze variant)
Compressor	Belt-driven + electric standby
Refrigerant	R452A (primary), R404A (optional, legacy support)
Standby power	230V AC (mains compatible)
Control system	Digital, fully programmable, lockable
Pull-down/recovery	<30 min to target (mid-load, 30°C ambient)
Evaporator/condenser	Composite-cased, corrosion-resistant
Data logging	Integrated, optional telematics/logging

The design places emphasis on recovery from thermal load events, a crucial demand for urban or high-frequency delivery use cases. Electrical redundancy (dual power sources), automatic fault monitoring, and door-activation input maintain consistent internal climates. Integration is possible with both OEM and retrofit installations using platform-specific hardware. Operators are able to select and programme both main and auxiliary zones, leveraging dual-evaporation for complex multi-product loads.

Which vehicles are compatible?

Compatibility extends broadly across the European commercial vehicle segment, including the Mercedes-Benz Sprinter, Ford Transit, Peugeot Boxer, Renault Master, Vauxhall Movano, Citroën Relay, and others. The SR200 system is engineered for installation within both new vehicles and as an upgrade for in-service models, supporting asset lifecycle extension and fleet harmonisation.

Conversion processes are calibrated for each chassis. For instance, high-roof models permit enhanced vertical airflow management, whereas LWB (long wheelbase) chassis support dual-zone partitioning without significant loss of usable volume. Right- and left-hand drive setups are both supported to meet regional regulatory demands. Conversion specialists such as Glacier Vehicles evaluate each deployment to ensure seamless electrical integration, correct insulation thickness (often 50–75 mm for chilled, up to 100 mm for deep freeze), and optimal compressor mount positioning, preventing interface conflicts with ancillary vehicle systems.

Industries leveraging brand-specific fleets—such as supermarket home delivery, clinical sample transport, or bakery distribution—can specify bespoke racking, multi-door access, or engineered bulkhead solutions. The SR200’s modularity thus permits detailed alignment with operational priorities, whether maximising urban delivery efficiency or ensuring GMP (Good Manufacturing Practice) documentation.

Where is this system used in industry?

The SR200 enables temperature compliance across a spectrum of tightly regulated and perishable value chains:

Food and Beverage

• Chilled and frozen route-to-retail (grocery, dairy, confectionery, meat, seafood)
• Event and venue catering with on-site delivery protocols
• High-frequency urban foodservice multipoint drops
• Bakery, patisserie, and ready-meal distribution requiring precise shelf life

Pharmaceutical and Clinical

• Transport of vaccines, biologics, blood products, and temperature-critical medical devices, with logging systems for audit trails
• Clinical trial materials shipped under GDP-compliant routes, often demanding compartmentalised van zones and strict chain-of-custody documentation

Floristry and Horticulture

• Rapid delivery for live flora, horticultural cuttings, and seasonal event installations, stabilised against humidity and thermal shock

Mixed-Use and Seasonal Sectors

• Pet food, beverage, or confectionery in dual-temperature fleet applications
• Event logistics (festivals, exhibitions) where high variability and loading cycles make fast thermal recovery crucial

Operators often contract with service partners (notably Glacier Vehicles in the UK) to align vehicle conversion and aftercare support, ensuring continuity as product lines or regulatory environments evolve.

How is installation and conversion performed?

Installation protocol is executed by authorised refrigeration van converters—firms trained and periodically audited for regulatory and performance compliance. The process comprises several key stages:

1. Chassis preparation: Dismantling of interior panels, surface cleaning, moisture barrier installation.
2. Insulation: Application of layered foam or styrofoam (thickness tuned to use-case), ensuring void-free coverage and prevention of thermal bridging.
3. Interior lining: Fitment of lightweight, antibacterial GRP panels, with wet lay resin for seamless joints and hygiene assurance.
4. Flooring and bulkhead: Installation of non-slip, waterproofed surfaces and secure partitioning; allows for dual-zone or triple-compartment setups.
5. Refrigeration system mount: Integration of compressor, condenser, evaporator, routing of plumbing and electrical, installation of digital controllers.
6. Electrical and data integration: Direct wiring to vehicle electrics, fuse boxes, and digital monitoring platforms as specified.
7. Commissioning: System vacuum and refrigerant charge, pull-down testing (unloaded and loaded), data logger calibration, and driver training.

Post-conversion, vehicles undergo multi-point QA inspection using temperature probes and airflow sensors to confirm uniformity. Documentation is supplied for regulatory inspection, and ongoing support or upgrades are facilitated through installers such as Glacier Vehicles, recognised for their detailed service protocols and customization.

How is the system maintained and operated?

Operation

Daily operation is simplified by the digital controller, which holds pre-programmed setpoints for multiple zones or different kinds of product. Drivers are trained to perform pre-shift checks on operating status, door sensors, and temperature displays. Many fleets adopt “pre-cool” protocols to ensure rapid pull-down before first loading, minimising temperature excursions.

Maintenance

• Routine: Service intervals typically occur every 12,000–20,000 kilometres or biannually, whichever comes first, and include cleaning of condenser, verification of gas pressure, door seal integrity checks, and control unit diagnostics.
• Adaptive: High-frequency, urban, or mixed-load fleets may require more frequent visits, calibrated by telematics or remote fault alerts.
• Preventative support: Use of predictive digital logging identifies compressor wear, fan anomalies, or rising pull-down times, allowing planned downtime.

Service contracts (especially for fleets converted by Glacier Vehicles) may include rapid on-site support, courtesy van provision, and integration with compliance management software. Documentation from each service, including log downloads and inspection checklists, is increasingly central to regulatory adherence, especially for pharmaceutical and food operators.

Why adopt this technology?

Organisations select the SR200 to address compliance requirements, maintain end-to-end product integrity, and optimise return on fleet investment. Specific points of differentiation include:

• Regulatory compliance: Integrated digital logging, audit-ready reporting, and firmware updates designed to keep pace with evolving sector standards.
• Operational efficiency: Swift pull-down and fast recovery between loads, minimising temperature excursions even during rapid, high-frequency routing.
• Modularity: Customization for single or dual-zone chilling or freezing, optional external standby, and racking tailored by operational profile.
• Lifecycle value: Long-term serviceability, component upgrade pathways, and design for recyclability to minimise total cost of ownership over the asset’s operational horizon.

The system’s limitations may manifest in extreme climate operation (requiring enhanced insulation or auxiliary cooling), or in highest-density payloads, where airflow management must be closely engineered. Fleets optimising both compliance and cost balance often elect for extended service contracts and digital upgrade options, provided through conversion experts such as Glacier Vehicles.

What compliance and environmental regulations apply?

A dense matrix of regulations and best practices governs every phase of SR200 deployment. Key frameworks include:

• GDP (Good Distribution Practice): Pharmaceutical cargoes must be maintained and monitored with high accuracy; logs and alarms are required.
• ATP (International Carriage of Perishable Foodstuffs): Vehicles must prove stable temperature cycles under tested payloads; certification is frequently renewed.
• ECWTA/ISO 9001: Quality assurance for conversion and ongoing operation.
• F-Gas Regulation: Refrigerant selection aligns with phasedown schedules (e.g., R452A chosen for low GWP).
• ULEZ/CAZ (Urban Compliance): In London and other European cities, low-emission vehicles are mandated—or heavily incentivized—impacting both the van and its refrigeration system’s energy profile.
• Hygiene codes: Construction, lining, and cleaning must prevent residue retention, bacterial growth, or airflow dead zones.
• End-of-life stewardship: Disposal and recycling of refrigerants and insulation materials are tracked, with increasingly strict record-keeping at environmental audit.

Operators engaged with ongoing product improvement often align with partners who monitor regulatory changes and drive early scheduling for compliance upgrades. Companies such as Glacier Vehicles play a vital role by providing regulatory-mapped installation certificates and update guidance.
