The S series Chillers are designed to cool processes with small heat loads.

They can be installed indoors or outdoors and can be configured to supply chilled water for

  • Potable water applications
  • Process cooling from an internal buffer tank
  • Process cooling to an external buffer tank


The chillers are supplied with – as standard

  • An internal 40L buffer tank to protect the compressor from excessive start, close temperature tolerance, reduces thermal spikes and allows for vented design with no need for hydronics kit
  • Suitable for indoor or outdoor installation
  • Rugged galvanized steel construction
  • Components sourced from the industries leading suppliers
  • R134a refrigerant for high ambient temperature operation and the lowest GWP of all contemporary refrigerants
  • Integrated circulation pump
  • Comprehensive 12 months warranty on all parts and labour
  • Highly accurate electronic controller
  • 316SS plate heat exchanger evaporator
  • Comprehensive factory testing before dispatch

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.

Close tolerance (CT)   The chiller can be manufactured with either a hot gas bypass valve for close temperature tolerance. Standard tolerance achievable is ±0.5C depending on load profile

The valve acts retard evaporator capacity as the chilled water temperature approaches set point.

BMS Connectivity The chiller can be connected to the high or low level BMS

Low level connectivity will be dry contact for

– Master run

– Master fault

High level connectivity is Modbus, SNMP and Bacnet over Ethernet without the need for a gate way

Potable water supply


The chiller can be manufactured to deliver water for potable water application. A typical installation requires the chiller to be connected to the main water and the pressure from the main is used to supply the process.
Remote Condensers


The chiller can be manufactured as a split system. The evaporator can be installed indoors in a plant room for example and the condenser installed outdoors.
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 units can be constructed with stainless steel cabinets, coil protection or copper lacquer doe example

The electrical enclosures are weather proof but if an enclosure is required with a high IP rating this can be offered

Castors The chiller can be supplied on wheels for ease of re-location

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.
