LCR-8-G2 Overview

K-O Concepts, Inc. catalog LCR-8-G2 water chiller bridges the gap between TEC and compressor based rack-mount recirculating water chillers. The LCR-8-G2 can cool heat loads at or below 800 watts w/ a temperature accuracy of ±0.1°C of set point. The LCR-8-G2 can be powered by 115V power that would otherwise require 230V mains. The volume of a LCR-8-G2 is 24-73% less than competing models.

K-O Concepts, Inc. LCR-8-G2 has been specially designed to cool CO2 lasers such as Synrad's firestar-V series and series 48 CO2 lasers.

SECOND GENERATION (G-2) rack-mounted water chiller. Maximum performance in a minimum package. Plug this “Lil” Chill cooling module into any single phase wall socket around the world. Specially targeted for direct diode & diode-pumped laser systems.

Easily Integrated
Standard 19 inch, rack-mounted configuration allows the cooling module to be integrated with the equipment to be cooled. Fully enclosed cabinet is equipped with handles for ease of installation. Weights from only 47 lb. / 21 kg. The chiller is air-cooled for portability.

Selectable Voltage
Field Selectable Voltage: 100, 120, 200, 208, 230 VAC, 50 or 60 Hz, 1Ø

Accurate Process Water Temperature Control
New 1/16 DIN “PID” controller offers more communication options and now has a visible symbol when controller is communicating with other devices. Maintains the desired process water temperature to within 0.1°C of set temperature.

Waste heat is harvested from the system’s compressor to quickly raise the temperature of the process water. Approximately 40% of the BTU rating of the chiller unit is available for heating the process water up to 50°C without any external heat load.

Communication Options
Standard RS-485 communications or optional RS-232, Modbus RTU or TCP, USB 2.0, DeviceNet or Profibus DP. Optional 2 Digital Input/Output alarm signals via communications.

CFC Free Refrigerant
All models use environmentally friendly R134a (HFC-134a) refrigerant. Chiller units using this refrigerant can be sold into Europe and Asia.

Process Water Pumps
Standard positive displacement (sliding vane) style process water pump with eight (8) speed settings provides flow from 3-10 liters per minute @ 70 psi (4.8 bar) available pressure. Optional centrifugal water pump with flow of 2-7.6 liters per minute @ 13 psi (0.9 bar) available pressure.

Optional Deionized (DI) Water Package
Includes nickel-brazed heat exchanger, ion (DI) cartridge assembly, water filter, and upgraded 316 stainless steel fittings. Easy service to the DI cartridge is accomplished from the rear panel.

Easy to Service & Maintain
Chillers are designed for easy service and maintenance. Convenient process water fill & drain features on all models. Access panels for ease of electrical service.

Free Standing Conversions Available
Converts rack-mount to free-standing chiller with casters.

End-User Printed Circuit Board
The EU-PCB monitors and reports interface signals via front panel LED’s, audible alarms and/or power down on any or all fault signals.

Optional Digital Pressure Gauge
The DPG is an upgrade to the mechanical pressure gauge. The transducer operates from 0-145psi and has a 0.25% BFSL accuracy rating. The transducer has all stainless steel parts with no o-rings. The controller displays “in-range” pressure values in green and “out-of-range” pressure values in red.
