Remote Alarm Pack (SA00001)

Used where the chiller is located some distance from the application, but an indication of chiller status is required close to the application.
Many users site the chiller away from the application, either in a separate room, an equipment chase, a plant room or outside of the building. The compact remote alarm pack is sited close to the application allowing the user to monitor the chiller, without the need to see the chiller. The display indicates normal operation, or shows alarms for temperature and fluid (both flow and level). An audible siren also sounds in an alarm condition. The pack is also fitted with an emergency stop switch that will turn off the chiller should this be necessary. The alarm box can be mounted up to 15 metres away from the chiller.

Low Temperature Pack (SA00002)

The Low temperature option can be fitted to allow the chiller to be operated below +4°C. This option will allow all chillers to be run down to -15°C. Please note that the cooling capacity will be reduced at these set temperatures (see individual cooling capacity graphs). The chiller must be used with Hexid A4, or a similar heat transfer fluid, to operate at these temperatures.

Heater Pack (SA00003)

It is possible to raise the operating temperature range of the chiller above 35°C by means of the Heater Pack. A heating element is mounted in the chiller reservoir and a dual outlet controller is used to provide accurate and efficient temperature control up to 65°C.

Water Cooling - Kt (SA00004)

This option can be built into all Kt Chillers and is used where you have a central or house water supply:

• Isolates the application from the house water supply (preventing contamination from elsewhere or damage from additives in the supply)
• Allows the use of alternative heat transfer fluids (eg H-Galden)
• Has a more accurate control of coolant temperature
• Allows the application to be cooled to a temperature other than the house water supply temperature
  
• Reduces air movement near the chiller (especially useful in Clean Room conditions)

Water cooled Kt Chillers require at least 6 litres/min cooling water at less than 25°C, with a differential pressure across the chiller of 1 bar.

Water Cooling -K1 & K3 (SA00005)

This option can be built into all K1 or K3 Chillers and is used where you have a central or house water supply:

• Isolates the application from the house water supply (preventing contamination from elsewhere or damage from additives in the supply)
  
• Reduces noise and warm air near to the Chiller
  
• Allows the use of alternative heat transfer fluids (eg H-Galden)
  
• Has a more accurate control of coolant temperature
  
• Allows the application to be cooled to a temperature other than the house water supply temperature
  
• Reduces air movement near the chiller (especially useful in Clean Room conditions)

Water cooled K1 and K3 Chillers require at least 10 litres/min cooling water at less than 25°C, with a differential pressure across the chiller of 1 bar.

Water Cooling -K4, K6 & K9 (SA00006)

This option can be built into all K4, K6 and K9 Chillers and is used where you have a central or house water supply:

• Isolates the application from the house water supply (preventing contamination from elsewhere or damage from additives in the supply)
  
• Reduces noise and warm air near to the Chiller
  
• Allows the use of alternative heat transfer fluids (eg H-Galden)
  
• Has a more accurate control of coolant temperature
  
• Allows the application to be cooled to a temperature other than the house water supply temperature
  
• Reduces air movement near the chiller (especially useful in Clean Room conditions)

Water cooled K4, K6 and K9 Chillers require at least 10 litres/min cooling water at less than 25°C, with a differential pressure across the chiller of 1 bar.

3 Phase Supply (SA00007)

Normally the K1 and K3 chillers operate on a single phase supply. ATC can build these chillers to operate on a 3 Phase power supply if required.
Kt chillers are only available as single phase units.
K4 and K6 can be supplied to operate on either single or 3 phase supplies.
K9 chillers are supplied as 3 phase units.

Non Return / Solenoid Valve (SA00008)

The non-return / solenoid option can be fitted to prevent back siphoning of fluid into the chiller when it is turned off for refilling or maintenance.
This option is recommended when the chiller and application are at different levels (more than 2 meters height difference), or where a long length of flexible tubing is used between the chiller and the application. It is also advisable to add this when the pipe-runs will be going up into ceiling ducts.

Low Flow Alarm (SA00010)

The optional flow alarm can be fitted where you need an indication that the flow of cooling fluid has failed. The switch is set at 1.5 litres per minute. A lamp will illuminate when a fault is detected and a buzzer will sound, if fitted.

RS 232/485 Comms and Software Pack (SA00011)

ATC Chillers can be supplied with communications ports (either RS-232 or RS-485) to allow continuous monitoring and logging of temperature and alarms by an external computer. The comms. port is via a 9 way D-connector. ATC can also supply a software package to perform the logging, allow easy archiving, show on screen temperature graphs and alarms, and view trend information. The package is easily configured and Windows compatible.

In-line Deioniser (SA00013)

For users who require very high levels of purity from their recirculating water ATC can offer an in-line deioniser, with all necessary fittings, mounted to the rear of the chiller. This will polish the recirculating water to better than 1 or 10 Siemens/cm. Cartridge expiry indication is by means of colour change windows (Blue - OK, Brown - Replace). A by-pass flow system is included to ensure that the flow rate through the cartridge is always optimal

Castors - Kt (SA00015)

Where mobility is required, Kt chillers can be fitted with castors. (2 locking)

Quick Release Self Sealing Connectors (SA00016)

All ATC Chillers can be fitted with self sealing, quick release fluid connectors. These are very useful when fast swap out of chillers may be required. The connector is released by means of a simple catch, which automatically closes the valve, preventing fluid spills. It is possible to disconnect one chiller and reconnect a replacement within 30 seconds, cleanly and efficiently.

ATC will mount one part of the connector to the chiller and supply the corresponding part in the accessory pack, for connecting to your tubing. The Quick Release connectors are compatible with all fluids used in the chillers.

Air Filter

A common problem with chillers is the blocking of the condenser (radiator) with dust being drawn in from the surroundings. It is vital to the healthy and efficient running of the chiller that this remains clear. Where the chiller is to be sited in dusty or dirty environments, or is to be mounted outside, ATC recommend fitting of the air filter into the K1 and K3 chillers. This re-usable or disposable filter is designed to make maintenance easier for the user and thereby extend the life of the chiller. The filter slides into the front panel of the chiller, and can be changed in seconds.

Stainless Steel Pump Heads

In certain applications where brass cannot be used in the coolant fluid system, ATC can fit a stainless steel pump head (SS303). When requested, all components in the chiller will be converted from Brass to stainless steel or plastic, in order to prevent any contamination. Pump performance will not be affected.

This option must be requested if an in-line deioniser is to be used in the recirculating system.
