Chiller Application

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.

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

All Thermex chillers up to 50kW 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 the 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.

Installation

There are certain guidelines that need to be followed to ensure the chiller operates properly and reliably. When considering the purchase of a chiller the site should be prepared so the chiller can be installed an operated reliably

The chiller should also be installed on a level firm surface and should be bolted down to prevent the unit moving. It is not necessary to install the chiller with spring vibration eliminators – waffle pad is suffice to prevent vibration from the unit

The water pipe work too and from the chiller should be properly insulated to prevent sweating and to ensure the chiller operates as efficiently as possible

There should be adequate space around the chiller to allow proper ventilation of the cooling fans – the chiller should not be installed under an awning or installed indoors if there is not proper ventilation.

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.

Options

High corrosive environments	If the chiller is to be installed in an environment with corrosive elements present the chiller can be manufactured in such a way to extend the life of the unit These environments can be – Coastal which high levels of salt spray present – Mining with Sulphur present The coils on the units can be coated with Blygold to extend their life – the coil will lose efficiency if the bond between the copper and the aluminum starts to break down and Blugold will prevent this In the case where flammable gas is present an Ex or ATEX rated unit maybe required
Soft starters	In installations where the power supply is not robust soft starters can be supplied on the compressors to limit the in-rush current on compressor start up.
Redundant pumps	The units can be supplied with 2 pumps that duty cycle to share the wear and tear. The software can also start the pump sitting in redundancy if the duty pump develops a fault
High Ambient	For installations such as mine sites, especially in remote areas where the temperatures are extreme the chiller can be constructed to be able to handle these extreme temperatures

WARRANTY

THERMEX Solutions warrants all it products for 12 months from the agreed commissioning date – no later than 30 days from invoicing date.
The warranty is to the first purchases of the unit
The warranty covers all parts and labour to rectify the unit
The warranty is subject to THERMEX Solutions terms and conditions which will be provided at the time of order
