Appointing and managing refrigeration Contractors - Guide
Selecting a refrigeration contractor- the process
Decisions: contract type, inclusions, budget
Pre tender questionnaire and screening
Selection criteria, interview, appointment
A working partnership
Selecting a refrigeration contractor- contract type, inclusions, budget
• Take your time• Prepare a full specification
– emphasise energy efficiency, reliability, safety
• Decide what should be included– e.g. capital works
• Contract duration– e.g. 3 years rolling
Selecting a refrigeration contractor- Pre tender questionnaire and screening
• Does the contractor:– understand the link between service &
maintenance and efficiency – understand the link between refrigerant and
efficiency– have an environmental policy which includes
energy efficiency improvement– have a refrigerant management policy, an
appropriate health and safety policy– employ qualified / experienced engineers and
provide them with appropriate equipment
Selecting a refrigeration contractor- Selection criteria, interview, appointment
• How would they devise the maintenance schedule?
• Do they have a track record of efficiency improvements?
• How would they improve efficiency/safety/reliability on your site?
Selecting a refrigeration contractor- A working partnership
• Listen to their recommendations– existing and new plant
• Staff training
• Audit their work
• KPI - energy consumption - refrigerant usage - number of breakdowns
Is your refrigeration contractor appropriate for your type of plant?
Other issues- health and safety in plant-rooms
• Where is your refrigeration plant located?• Is the lighting adequate?• Do you send service engineers in there alone?
Other Issues- Specifications
• Does it simply list regulations and directives?
• Does it make responsibility clear?
• Important elements can easily fall between the owner and the contractor
Recap:
• The reliability of your refrigeration plant is essential to your business.
• Selecting the right contractor for you can save you £’s
• Don’t leave the selection and monitoring to chance
And finally
• Although the theme today is ammonia refrigeration, is it essential that all users of refrigeration systems are aware of the forth-coming R22 phase-out
• When selecting and monitoring contractors ask them for their advice for any non-ammonia systems that you have.
• If they don’t provide any – seek it elsewhere.• Don’t leave it too late.• F-Gas
