Ammonia Refrigeration Maintenance
We at Maximus Chillers are adept in the niche of ammonia refrigeration. We have expert engineers who have the capability to fault find issues quickly and correctly. We have engineers in the Manchester area and a network of customers around the UK and the world.
Spiral Freezers
Some food products can be as hot as 230°C when they come of an oven, they then need to be cooled down to -25°C. This is a large amount of sensible heat that needs to be removed. This heat also has to be removed fast to prevent bacteria from being able to grow. Ther best solution for this application is a spiral freezer. When the food product comes out of the end of the spiral freezer, it is ready to be packed and shipped.
Ammonia Refrigeration Food Production Factories
For all kinds of food production applications, we have years of collective experience on an in depth level. Some of our customers have multiple machine rooms to house the compressors around the factory. Other of our customers have just one compressor. From large to small plant- we can find the solution that is right for you. This will save money over a time which can be better invested in driving your business.
Ammonia Refrigeration Cold Stores
The fan coils in our coils in cold stores absorb heat from the store which has ingressed through he thermal insulation and also from the food product which is entering the store. Repeated opening and closing of the doors from personnel entering and leaving with the product also adds heat load to the store. This heat load calculation was worked out when the plant was installed.
Case Study of Ammonia Refrigeration Maintenance
A customer of ours in the Greater Manchester area contacted our office with a loss of production issue at his food production factory. We promptly arranged for one of our engineers to attend site…
Permit to Work in Ammonia Refrigeration
On arrival he filled in the necessary paperwork regarding infectious diseases and signed the permit to work. Our site contact showed him to the spiral freezer which had the issue.
Ammonia Liquid Pump Failure
One of two ammonia liquid pumps had thrown the breaker in the electrical panel. On inspection with his multimeter, our engineer found that the electrical windings had blown to earth.
N+1 Controls Switch Over
As the ammonia liquid pump is critical to the operation of the plant, a redundant system is available. The control panel automatically switches over to the redundant pump.
Remove and Replace Pump Motor
The power supply was isolated, locked off and tagged out according to the procedure set out in our Method Statement. The mechanical part of the pump was then valved off. The shaft coupling was unbolted from the electrical motor. The electric motor was then replaced with stock from the onsite stores and the electrical connections were re-made with new connectors.
Re-instatement of Ammonia Refrigeration
The valves were then opened and a leak test was carried out. The cam switch on the control panel was switched over to start the new pump motor and the electrical readings were logged on the commissioning sheet.
Customer Satisfaction
After the job was signed off, the customer wated to talk to our engineer about the technical side of the job. He asked about the frequency of electrical testing. Our engineer explained to him that all wiring is tightened on each maintenance visit and the amps taken of the various components. Where the amps are higher than expected, further tests are carried out to help prevent failures occurring during production.
Why Choose Us for Ammonia Refrigeration Maintenance?
Just look at our pump out unit as an answer to this question. We can transfer any amount of anhydrous ammonia from your plant. We can recycle and supply fresh ammonia from our UK facility.
Each engineer has the Maximus app on his phone which relays information in real time to The Office in Manchester. Parts manuals and operating and maintenance manuals can be sent out using this app which speeds up the fault finding process on site.
What We Offer for Ammonia Refrigeration Maintenance
We believe our Tick Sheet is the best in the industry. Every fault can be found by checking the values and using a refrigerant comparator. This means we can offer the maintenance of your plant at a competitive price.
Smart and efficient engineers who are customer orientated. We will always go that extra mile when it comes to helping our customers. We are accustomed to induction days and permit to work training prior to starting any works
Each of our contract customers can call our Technical Support desk to be talked though remotely. This can often save you the cost of a call out. Less call outs means more money in your budget. We can do video calls to walk through, talk through faults with our customer next to the plant. This means that our engineer can arrive onsite with the necessary parts and materials to get you up and running fast!
