K-O Concepts Models CS
K-O Concepts Inc. Chiller Part Number	2542-2700
Cooling Type	Refrigeration w/ hermetic compressor.
	Motor type:  24 VDC input w/ electrically commutated motor.
Refrigerant	R134a (HFC-134a). Refrigerant is CFC- Free.
Process Coolant Pump	Model MD05:   w/ 24 VDC electrically commutated motor.
Pump type: Centrifugal, magnetically coupled	Note:  Pump body is  fabricated from engineered plastics.
(seal-less), water pump.	Note:  See performance curves on following page.
Process Coolant Connections	Two sets of process coolant connections:  Connections via Colder
	Products LC series quick-couplings as defined by customer.  See K-O
	Interface Control Drawing (ICD) part # 2543-2700.
Process Coolant Temperature Range	5.0-7.0°C (typical) with two laser delivery hand-pieces installed.
Cooling Performance	Process coolant depression from 30-15°C:  20 minutes (typical).
Note:  Performance w/ ambient air @ 30°C	Minimum coolant temperature: 5.0-7.0°C (typical).
Process Coolant Temperature Stability	±0.5°C (typical)
Heat Dissipation	To air (air-cooled)
	Note:  Chiller module requires customer fan after installation into
	cabinet.
Condenser Fan	Motor type:  12 VDC input w/ electrically commutated motor.
Condenser Fan Control	Chiller utilizes a speed-controlled fan for improved coolant
	temperature control over ambient air temperature range.
Environment	Indoor operation w/ unrestricted ambient air from 15-30ºC/59-86ºF.
Process Coolant	70% distilled water / 30% isopropyl alcohol.
Process Coolant Capacity	33 oz. / 1.0 liters
	Note:  Volume does not include hand-pieces or external fill bottle.
Coolant Drain	Coolant drained with chiller pump via drain tube provided.  24 oz. / 0.7 liters is typical coolant recovery volume.
Heat Exchangers	Condenser:  Refrigerant to air heat exchanger (tube & fin design).
	Condenser coil removes heat from refrigerant via fan.
	Evaporator:  Refrigerant to water heat exchanger (brazed-plate design).
	Evaporator transfers heat from coolant.
Input Power Requirements	24.0 VDC @ 5 amps (typical). Voltage range:  22.7-31.5 VDC.
	Note:  150 watt switching converter power supply optional.
Electrical Interface Signals	Signals (N.C. / normally closed in passed condition):
Note:  All interface signals are contact closures.	Process water flow (dual channel) & process water level.
Note:  Flow & level switches are reed switch
type.
Process Coolant Flow Switch	Set point value:  200 cc/min (each channel).
Note:  Device monitors process coolant flow	Process coolant flow below set point value opens contact.
through each of “2” customer hand-pieces.	Note:  Pump power should be removed if both switches are open.
Process Level Switch	Process coolant level switch allows for 8 oz. / 0.25 liters loss of coolant
Note:  Device monitors process coolant level in	before opening contacts.
coolant tank.
