DMC-30-G2 Overview

K-O Concepts, Inc catalog DMC-30-G2 rack-mount water chiller can cool heat loads from 3,200 watts. These industrial process water chillers have been designed for laser, laboratory, medical, and manufacturing cooling. The DMC-30-G2 has advanced temperature control that is able to maintain ±0.1°C of set point. The volume of a DMC-30-G2 is 58-66% less than competing models.

K-O Concepts DMC-30-G2 is designed to cool CO2 lasers such as Synrad's firestar-f200-f201, evolution 125-200 series CO2 lasers.

SECOND GENERATION (G-2) rack-mounted water chiller. 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. Weighs 94 lbs. / 42.7 kg. The
chiller is air-cooled for portability.

Accurate Process Coolant Temperature Control
The “PID” multi-loop controller accurately maintains the desired process coolant temperature to
within 0.1°C of set temperature. The dual digital readout on the User Interface module displays both
set and actual process coolant temperatures.

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 6 Digital Input/Output alarm signals via communications.

CFC Free Refrigerant
All models use environmentally friendly R134a (HFC-134a) refrigerant for mobile applications.

Process Coolant 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 positive
displacement (sliding vane) style process water pump with seven (7) speed settings provides flow
from 6-16 liters per minute. Optional centrifugal water pump also available.

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 coolant fill & drain
features on all models. Access panels for ease of electrical service.

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.
