The ETS Model 563 Gas Cooling System enables the temperature within the
Model 518 Chamber to be reduced below ambient.
1. The System utilizes Liquid CO
2
* (Carbon Dioxide) as the cooling medium.
CO
2
is user supplied. 50lb. CO
2
tanks are readily available from local
bottled gas companies.
Liquid CO
2
with a DIP Tube must be specified. The DIP Tube allows
liquid to be siphoned from the bottom of the tank. CO
2
Gas (without
DIP Tube) will not provide cooling with this system.
2. The CO
2
is allowed to evaporate (expand from a liquid to a gas) within the
chamber.
3. The phase change of the CO
2
produces a large cooling effect. (The
temperature directly in front of the nozzle will be near -100 °F.)
4. The microprocessor temperature controller will monitor the chamber
temperature and proportionally control the solenoid valve to provide the
appropriate amount of cooling to maintain the desired set-point.
4.2.1.1 Cooling System Accessories
1. Liquid CO
2
Transfer Hose
A. 4’ long with Braided Stainless Steel Safety Shield.
B. Brass High Pressure Fitting for mating to Liquid CO
2
tank.
C. Brass Quick Disconnect (female) for mating to Valve Input.
2. Cooling Nozzle Cleaning Tool
4.2.1.2 Liquid CO
2
Tank Connections
1. Secure the CO
2
cylinder to a wall using an approved securing belt or
clamp.
2. Failure to secure the cylinder to a wall or other suitable stationary object
may result in serious injury to personnel should CO
2
cylinder fall over.
3. The CO
2
cylinder contains liquid carbon dioxide under extremely high
pressure (800-1000 psi). Care must be exercised at all times when
working with this cylinder. The manual valve on top of the cylinder should
be closed (fully clockwise) when the cooling system is not in use.
