INDUSTRIAL WATER CHILLERS – 1 to 4kW UNITS
AIR COOLED

Thermex Solutions is Australia’s largest manufacturer of small specialsied industrial water chillers

Industrial process chillers are designed to circulate water to a heat producing process via a water pump. The water brings the heat back to the chiller where the compression cycle cools the water before it is returned to the heat process.

They are typically not for potable water applications although the chiller can be designed to supply potable water.

All Thermex chillers up to 100kW are supplied with a buffer tank – the buffer tank is an important feature in all chillers and the bigger the better. The buffer tank in a process chiller has many benefits such as
• helping protect the compressor from excessive starts
• preventing thermal spikes impacting on he compressor
• allows closer temperature tolerance to the process
• having stored chilled water to allow a managed shut down of a process should there be a problem with the cooling cycle
• allows for a vented design and prevent the need for a hydronics kit

All Thermex process industrial chillers are supplied with high efficiency scroll compressors supplied by Copeland. The scroll compressor is the latest in compressor technology

All Thermex water chillers use R134a refrigerant – R134a is a contemporary refrigerant with a low global warming potential. R134a refrigerant also has the benefit of being a low-pressure refrigerant gas – this allows Thermex chillers to operate in extreme ambient conditions- up to 52°C. Chinese and European manufactured chillers are rated at 35C ambient condition and are generally supplied with condensers that are not suited to these extreme conditions.

TECHNICAL DATA

The units are designed to be installed with equipment with small heat loads. Typical installations include

  • Analytical equipment

Pump Performance

The unit will usually be supplied with a primary circulating pump as standard

Thermex can customize the pump for particular applications and these should be specified at the time of order

The unit has an internal water bypass designed to protect the heat exchanger – it should not be closed under any circumstances

The flow/ pressure charts for the standard pump are shown above

All operational cooling capacity, power consumption and current draw data shown above is based on the chiller operating at the limit of its design and is intended to be an indication only.

Each chiller will be individually designed to customer requirements and a detailed product specification will be supplied at time of order including installation instructions and dimensions. The power consumed by the unit and the current it will draw vary depending on how the chiller is constructed. The chillers performance may also vary slightly from the figures above again based on customer requirements.
