Chiller 2017102019 59ea556fa6c69 1200x480 - Chiller

A chiller is a machine that removes heat from a liquid via a vapor-compression or absorption refrigeration cycle. This liquid can then be circulated through a heat exchanger to cool air or equipment as required.

A 5-Step Plan to Chiller Efficiency in Your Temperature Controlled Food Business

A Chiller is a significant capital investment, and a chief contributor in your temperature controlled business. For many businesses, chillers are the single biggest energy consumers, as such the need for comprehensive maintenance to ensure their longevity, and continued efficiency, is very high. So, does your chiller need maintenance?

At Glacier Vehicles we offer full maintenance for your chiller, at very affordable prices. Interested? We are just a phone call away, feel free to contact us on 0208 668 7579, to enjoy our professional services

A 5-Step Plan

To continue to get the best out of your chiller, prudent maintenance is key. At Glacier Vehicles, we do much more than just routine maintenance. We understand the rudiments of chiller maintenance, as well as the importance of details. Our 5-step plan is a testament to our commitment to excellence. Take a look at the plan:

1. Start and Manage a Daily Operating Log

Daily performance of the chiller must be documented with an accurate log, and compared with design and start-up data for problem detection. This procedure allows you to amass a history of its operating condition, which is analysed for trends and patterns. This allows for a forecast of potential problems

For instance, if there is a gradual increase in the condensing pressure of your chiller in a particular month, you can consult the operating log and have a thorough check, to uncover the possible cause of the problem. Appropriate rectifications can then be made.

2. Keeping the Tubes Clean

One possible obstacle to get your desired chiller performance is the efficiency of heat transfer. The performance of the chiller, and its efficiency, is connected with its ability to remove heat, which can be achieved through neat condenser tubes and evaporators. Large chillers are comprised of a sequence of tubing, so keeping their surface tidy is vital for maintaining efficient performance.

There are two main methods for cleaning chiller tubes:

  • Mechanical Cleaning: This process removes loose particles from the bore tubes, scrubbing the tubes and flushing with water.
  • Chemical Cleaning: This process removes scales. Consulting with a water-treatment provider is recommended for this method.

3. Ensuring a Leak-Free Unit

Most manufacturers recommend that you test your compressors for leaks every quarter.

Non-condensables are stuck in the condenser, once they are in the chiller.  They increase the pressure of the condenser, the requirements of the compressor, and reduce efficiency of the chiller. Low-pressure chillers are highly efficient in removing non-condensables, this will help maintain the required condensing pressure, and efficiency.

4. Analyse Oil and Refrigerant

Regular analysis of your oil refrigerant will help in catching  contamination problems, before they become more serious. Proper analysis entails testing for spectrometric chemicals, to determine pollutants, which hinder performance efficiency.

5. Sustain Proper Water Treatment

Chillers transfer heat through water, therefore, proper water treatment is non-negotiable. Chillers with cold water systems are often treated chemically.

With the right maintenance managers, proper water treatment should be a non-issue. Why not call us now to find out more.
