Kodiak Chiller Options

Option Benefit
 Chiller Protection Options 
 External flow valve: HIGHLY RECOMMENDED. A manually adjustable globe valve installed on the back of the chiller in parallel with the chiller coolant supply/return. Allows the operator to control the flow rate to the application. As the external flow valve is opened, more of the flow bypasses the application.
 External pressure relief valve: A manually adjustable pressure relief valve (50 to 100 psi or 0 to 50 psi) installed on the back of the chiller in parallel with the chiller coolant supply/return. Allows the chiller to continue to run and maintain temperature if the flow to the application is interrupted. When flow to the application is stopped, the pressure relief valve opens and bypasses flow to the chiller’s return. It can also be used to prevent the chiller supply from exceeding a predetermined pressure setting.
 Anti-siphon system: Check and solenoid valves installed internally to the chiller on the supply and return lines, respectively, with the exception of the RC095 and RC115, on which they are installed externally by the customer. Allows the chiller to be installed at an elevation below the application. Prevents backflow and subsequent overflowing of the chiller’s vented tank (if not installed, fitting leaks in the application can allow air to displace the coolant, resulting in backflow to the tank).
 Air filter: Internally mounted on the air inlet to the condenser coil. Filters incoming air to the chiller’s condensing coil, preventing dust build up which can lead to decreased performance. The easy-access filter is simple to replace, reducing the need to clean the condensing coil and refrigeration components.
 5 micron coolant filter: Externally mounted on the supply from the chiller. Filters process coolant being supplied to the application, protecting equipment from blockage or damage due to particulate buildup and extending pump life.
 Special Applications Options 
 Heater: Submerged 2,000 Watt electric resistance heater with built-in over temperature shut-off (non-adjustable). Allows chiller to reach elevated set points faster (useful for applications in cold start-up situations or where the coolant set point is frequently cycled). This feature does not extend the coolant temperature range of the chiller.
 Internal insulation package: Insulated tank, pump head, and coolant lines. Eliminates condensation forming on the components in contact with the fluid when operating chiller at set points below the ambient dew point.
Low temperature operation: Chiller coolant temperature range is –5°C to +25°C (23°F to 77°F) for RC009-RC045 models and -10°C to +35°C (14°F to 86°F) for RC095 - RC115 models (Note: internal insulation package must also be selected). Optimizes performance for low temperature operation and provides additional low temperature cooling capacity compared to standard chillers. Contact Lytron’s applications engineering department for performance graphs.
 Water-cooled condenser: Refrigerant is condensed using water (rather than ambient air) via a liquid-to-liquid heat exchanger. Heat that would normally be rejected to the ambient environment is transferred to an external liquid coolant source, avoiding room warming and possible air conditioning overload. Also, water-cooled chillers are quieter because there is no condenser fan. Contact Lytron for required facility liquid coolant flow rate and temperature requirements.
 0.1°C set point: Allows 0.1°C increments of the set point and display temperatures. Allows more precise control of the coolant delivery temperature. Available in °C only.
 Fluid Compatibility Options 
 Deionization Package: Externally mounted DI cartridge (no indicator light) on the return to the chiller. Filters ions from coolant to maintain a fluid resistivity level between 1 and 3 megohm/cm by partial flow through the resin bed. This feature does not include a resistivity indicator light. High purity plumbing is recommended with the DI water cartridge.
 High purity plumbing: Includes nickel-brazed evaporator and nickel-plated or nylon fittings compatible with DI water. Not compatible with brass pumps. All wetted materials are fully compatible with DI water to prevent component corrosion.
 PAO compatibility: Includes pump, fittings, hose, and oil filter compatible with polyalphaolefin (PAO). Anti-siphon system and internal insulation packages are included in this option. All wetted materials are fully compatible with PAO. Contact Lytron for PAO performance curves.
 Chiller Convenience Options 
 Remote start: Chiller power can be cycled through a computer or relay. Allows an external circuit to control the chiller on/off function via dry contacts on the rear of the chiller.
Please refer to the chiller technical manual for further discussion of these features.

Kodiak Chiller Controllers

Controller Option Functionality Controller Package
Digital temperature display  Easy-to-read display in either °C or °F. All
Calibration offset  Allows temperature display to be offset to represent the temperature at a different point within the cooling circuit. 1,2,3
Low flow shut-off fault  Alerts user to a lack of coolant flow and shuts down the chiller to prevent the refrigeration system from freezing. All
Auto-restart  Automatically returns chiller to its operating status prior to interruption of power, e.g., if the chiller was on, it will turn back on when power is restored. All
°C/°F toggle  Enables temperature display to be viewed in °C or °F. All
Audible alarm  Audible warning of all fault conditions. 1,2,3
Alarm mute  Silences audible alarm until the alarm is cleared or the chiller turned off. 1,2,3
Digital pressure sensing  Displays pump output pressure (psig or bar) and allows it to be transmitted through RS232. 2 - 9 Plus A
Low level fault  Alerts user that the coolant level in the reservoir is at a critically low level (approaching the level of the pump’s suction line). Switches chiller off if ‘fault shut-off’ is on. 2,3
Low/high temperature fault  Alerts user that the coolant temperature is outside of the user’s defined set-point limits. Switches chiller off if ‘fault shut-off’ is on. 2 - 9 Plus A
Low/High refrigerant pressure visual alarms Protects the compressor from high pressure due to excessive heat buildup in the refrigerant and also from a low refrigerant suction pressure condition. 4 - 9 Plus A
Remote set point and retransmission Provides for either a 4-20 mA or 0-10 VDC analog signal to change the coolant set point based upon the process cooling requirements. 8 and 9
Fault shut-off
(toggle on/off)
Allows chiller to be programmed to shut down on fault (on) or continue to run during fault conditions (off). The chiller will always shut down on the low flow shut-off alarm. 2,3
Single Relay contacts
(normally open or normally closed)
Fault conditions of the chiller can be monitored by applying a low voltage power signal across dry contacts at the rear of the chiller. (Power loss to the chiller is not a fault condition.) * Mating connector—AMP part number 350715-1 and 350547-1 2,3
Multiple Relay Contacts Via the 25 pin connector, provides multiple dry contacts for customer signals for coolant over temperature, reservoir low level condition and pump low flow condition. 5 - 9
RS232 communications and /or RS-485 communications Allows complete control of all the chiller’s controller features (changing/monitoring coolant set point, monitoring pressure, and fault alarms, etc.) from a remote computer for monitoring, control, and data logging. 3,6
Ethernet communication    Provides chiller control/monitoring via Ethernet communications. A
Package 2 is the standard package for RC006 to RC045 Kodiaks.
