Air Condition

aermec 50 yearsAermec provide a wide range of process chillers with free cooling to meet all manufacturing needs. It makes sense if you can cool water free then its saving you money and you reduce you CO2 emissions to the environment.

NRL free cooling water chiller

Aermec have developed water chillers that operate in the conventional way of using a refrigeration circuit to cool the water and avail of opportunities when the outdoor temperature is low enough to a cool the water without the need to operate the refrigeration circuit. As the outdoor temperature increases to between 5 – 16oC an 3-way valve and electronic expansion valve within the chiller allows partial use of the refrigeration circuit to meet the demand. As the outdoor temperature increase, further the chiller refrigeration circuit meet the full cooling demands.
By limiting the use of refrigeration circuit in cooler days and nights takes advantage of the renewable (free) energy sources with annual energy savings of up to 60% can be made and reducing payback periods

There are basically two types of Water Chiller – Air Conditioning (AC) and Industrial Process Cooling (PC) chillers.

Aermec NRL process water chillerAC chillers are generally installed in sealed and pressurised systems, which require auto air vents, expansion vessel and a mains water supply through a filling valve or pressurisation unit. They generally have small volume buffer tanks and a low pressure water pump to suit a cooling coil in an AHU, but high pressure umps are also available. Aermec provide a vast range of AC chillers.

PC chillers such as the CTA CPE and IPEO are supplied with an ‘fill & vent tank (make up tank)’ which eliminates the necessity for a mains water supply, expansion vessel and auto air vents, due to the self priming process.

These PC chillers also come with a high pressure pump (i.e. 3 bar) and with a large volume buffer tank to prevent short cycling and provide a very stable supply temperature. CTA provide a large range of process cooling chillers.

In certain circumstances, Aermec chillers are also used in process cooling applications, often in conjunction weir tanks provided by EICL.
