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.

Dimension

Selecting the Chiller

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 standard pump supplied with the chiller is sized to produce 350kPa of pressure external to the chiller at the required flow rate

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

Pump model	Current draw – Ph	Motor rating – kW	Model	Power
P1	3.1	0.5	TC03	1 Phase
P2	3.1	0.5	TC05 to TC12	1 Phase
P4	4.0	0.85	TC15	1 Phase
P5	5.2	1.2	TC18	1 Phase
P6	4.6	2.2	TC20 – TC30	3 Phase
P7	4.8	2.2	TC40-TC50	3 Phase
RPM	2900
Approvals	CE, WRAS, ACS, TR, EAC
Housing	Cast iron
Impeller	Stainless steel 316

Options

Close tolerance (CT)

The chiller can be manufactured with either a hot gas bypass valve or a VFD on the compressor for close temperature tolerance. Standard tolerance achievable is ±0.5C depending on load conditions

The valve acts as to unload the refrigeration effect to the evaporator as the chilled water temperature approached set point.

If the compressor is fitted with a VFD this will slow the compressor down as water temperature approaches set point and speed it up as it approached set point plus hysteresis. The software has a PID loop to ensure maximum efficiency and maintain temperature control.

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

Tandem/ N+1 (T)

The chiller can be wired if they are to be installed in a N+1 arrangement so the lead chiller manages the duty cycling of the chillers and controls the chillers if a fault should develop in one of the chillers

Potable water supply

(I)

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.

The chiller will have a heat exchanger installed which will cool the mains water to the supply temperature in a single pass

If the process does not require water the chillers operation is unaffected

This method of construction also allows the chiller to be used to cool water temperatures above 25C

Remote Condensers

(R)

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.

Typically, the maximum distance between the 2 halves of the chiller is 20 meters – for longer runs contact Thermex’s engineering staff

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.
