Chiller Refurbishment Diagnosis

Our engineers are in their comfort zone while carrying out diagnosis during chiller refurbishment- that is what they do best! Even when a fault involves wiring that disappears into a loom, down the other end of the machine, with no wiring diagram- Maximus Chillers can help. Usually, however, faults are obvious to our engineers or can be found easily.

Technical Support Desk

Our contract customers enjoy the full benefit of our global technical support desk. We offer real time technical support with manuals being sent electronically to site. Where a time difference is involved, we arrange a time convenient to both locations, or answer emails when the office opens in the morning. If we can talk you through over the phone, we can get you up and running with the minimal disruption to your process.

An R407c chiller condenser retrofit lifting operation outside in the compound

R407c Chiller Condenser Retrofitting

We recently undertook the job to carry out bespoke R407c chiller condenser retrofitting in the North West.

Rusted and Corroded Condenser

The old condenser looked alright on the surface- the fins were in good condition. The condenser was 18 years old, however, so when an attempt to repair a leak was carried out- the condenser leaked further along. This is because of the warming of rusted and corroded copper with an oxy-acetylene torch.

R407c Chiller 'V' Condenser Retrofitting

We arrived on site to measure up for the job. The ‘V’ condenser was built to order. We manufactured an exact replica to the same specifications and sizes of the old one. The operating pressures and high pressure cut out limit were taken into account in the design and the use of materials.

Lift Out of the R407c Chiller Condenser being Retrofitted

On the day of the lift and shift we isolated the panel and checked it was dead, then we removed the panel and laid it on its front. This was to access the rivets behind the panel. These rivets, the ones on the other end of the chiller and around the lid were removed using a tool. The fans were disconnected and removed to make the lid lighter to lift off. Then, we attached slings to the chiller condenser and lifted both halves of the 'V' out.

Lift In

This part we did not want to get wrong as the condenser was brand new and did not have a mark on it. A reverse of the removal- it fitted perfectly just the same as the old one. With the lid lifted back on and the fans in- time for brazing then the pressure test.

Pressure Test, Dehydration and Recharge

The pressure test was satisfactory so our engineer put the system on vac for dehydration purposes and the removal of non condensables. After a deep vacuum was achieved the system was recharged and run tested. No issues were found.

Chiller Refurbishment Company

Choosing a chiller refurbishment company is cost effective because the main cost of a large chiller is mostly in the fixed plant. That is to say: the two main heat exchangers and the compressor. Therefore, this is the most environmentally friendly option as the carbon footprint of building new plant is very high. This is not mentioned when you purchase a new chiller. With chiller controls replacement, this kind of plant can last for 50 years. One of our competitors has been carrying this out to a chiller that dates back to the 1970s and is still in service!

Chiller Evaporator Refurbishment Company

Refurbishment of broken tubes can be performed to beyond manufacturer's recommendations. Larger scale replacement of the tubes can be carried out giving the same lifespan of the original tubes. This is a major overhaul at a fraction of the cost of replacing the chiller.

Chiller Compressor

We strip the chiller compressor down in our workshop. It is made from heavy castings so will last a very long time. We provide a 12 month warranty on all our chiller compressors. Read More about centrifugal compressor remanufacturing on our web page.

Chiller Controls

State of the art controls can be fitted. The controls that come with the chiller are often made 'in house' so they can be prone to spurious trip outs. These trip outs can cause a loss in production. A control panel designed specifically for that chiller comes ready built. All you have to do, is wire in the various sensors and transducers. The run signal, compressor soft start, remote loading and monitoring can be easily integrated. Simple and easy solutions to big problems are what we do!
