Yes, or supply you with a new one. We stock all makes and models of chillers.

While there are many makes and models, the age of the chiller will determine whether or not it can be effectively repaired. However, having said that, we can usually repair most chillers, to full restoration.

Yes. We design water cooled and air cooled chiller systems – complete with piping, pumps and cooling towers.

A refrigeration system used in a commercial or industrial facility - like a perishable food cold room or in a manufacturing plant.

The working fluid in a refrigeration system, such as ammonia or chilled water.

A wide variety - from small "plug-in" vending machines, display cabinets and food service coolers to large supermarket refrigeration systems.

The controlled cooling of products, mechanisms and factory machinery in many different industries.

A wide range of industries – including Plastics, Metal working, Chemical processing, Pharmaceuticals, Food and Beverage processing and Paper processing.

A single large chiller that serves multiple cooling needs.

A series of compact chillers, each serving a separate application or machine.

Water cooled, Air cooled and Evaporatively cooled.

A mechanical chiller is powered by an electric motor, steam turbine or gas turbine.

Reciprocating compression, centrifugal compression and screw driven compression.

Evaporator, compressor, condenser, expansion valve.

Yes, we supply all types and specialise in CAREL programmable controllers.

Yes. We design control systems according to our clients’ requirements using the latest technology. We specialise in CAREL programmable controls.

Yes, we design and draw complete wiring diagrams.

Yes, we build electrical panels for any application, according to our clients’ specifications. We can incorporate variable speed drives, soft starters, direct online starters, star delta starters, relays, timers, UPS, voltage and ampere indicators.

Yes. We design air-conditioning complete with ducting, dust air handling units, split systems, VRV systems, VAV systems or Package systems.

Any form of technology that modifies the condition of air - such as heating, cooling, dehumidifying, cleaning, ventilation or air movement.

The creation of an indoor environment that remains relatively constant in a range preferred by humans, in spite of changes in outside weather conditions or in internal heat loads.

The provision of a suitable environment for a commercial or industrial process being carried out, regardless of internal heat loads and external weather conditions.

Wind speed increases significantly at higher altitude. This makes natural ventilation impractical for very tall buildings.

It filters the air to high levels to reduce infection risk. It also controls the humidity to limit patient dehydration.
