PureGuard LVP Gas Temperature Control System
Download PDF Data SheetThe PureGuard gas temperature controller coupled with the PureGuard cylinder jacket is a reliable system to control the temperature of your critical high purity process gases.
The PureGuard temperature control system is capable of controlling to +/- 0.05* Celsius; using a compressor free solid state cooling system in an energy efficient, compact package.
Typical applications are for low vapor pressure gases as those used commonly in CVD and Etch.
The PureGuard gas temperature control system has a built in recirculation pump that pumps fluid through a heat exchange jacket. The controller maintains fluid temperature either cooling or heating depending on the need using a completely solid state technology.
System Attributes
- Compact Control Module (~12” square)-No CFC’s or Compressor Maintenance
- Solid State Thermal Technology-Lower Power Consumption
- Heat resistant Kevlar Jacket with Polyester Outer Provides the Ability For One Jacket to be Used on Many Cylinder Sizes
- Full Surface Insulated Contact for Maximum Efficiency
- Power: 115-230VAC, 50/60Hz, 7/5A
Compare PureGuard to the Competition
Feature | PureGuard | Competition | Decision | Key Differentiator |
---|---|---|---|---|
Price | $11,700 | > PureGuard | PureGuard | PureGuard is less costly |
Power Consumption | typical <200 watts | 2875 watts | PureGuard | PureGuard more efficient from cooling technology & heat exchanger |
Maintenance | Maintenance Free | Compressor Maintenance | PureGuard | Thermoelectric lifetime exceeds 200,000 hours, recirculation pump 25,000 hours |
Accuracy | 0.05° C | 0.1° C | PureGuard | PID and Variable power output allow for more accurate control |
Temperature Controller | PID with Variable output | PID Controller, On/Off cycling | PureGuard | System can control power output for fine control, not just on and off |
Temp Control Technology | Solid State Thermoelectric Technology | Compressor Based | PureGuard | Solid State technology doesn’t require maintenance, has no refrigerants for disposal or ozone depletion, uses only energy required to control temperature, not typical full on then completely off type thermostat |
Refrigerant | None | R-134a | PureGuard | Thermoelectric design does not use compressor or refrigerant |
Jacket Design | Soft Nomex outer shell, stainless vertical coils | Stainless Hard jacket with fluid channels | PureGuard | PureGuard soft design allows for same jacket to be used in multiple applications, also heat exchanger has much more contact area with bottle for better heat transfer. |
Jacket Ease of use | Soft Nomex outer shell, stainless vertical coils | Stainless Hard jacket with fluid channels | PureGuard | PureGuard will fit securely around any similar sized bottle with straps allowing to snug the jacket. AGT’s hard jacket not compliant with bottle that might have surface features and will allow for air gaps. |
Communications | RS232 Standard | RS232 or 485 Optional | PureGuard | PureGuard comes standard with communication package |
Power Requirements | 90 to 250 VAC | 115 VAC or 230 VAC | PureGuard | AGT must be ordered for correct power region, PureGuard is Universal |
Size of Controller | 12.75″ x 11″ x 12.75″& 28lbs | 28.5″ x 16.5″ x 16.5″ & 127 lbs | PureGuard | More Compact design, less space requirements, can be moved easily |
Noise | 49dba to 63 dba @ 3 feet | Not Published | PureGuard | PureGuard has variable speed fan, normal running 49dba, will increase speed as needed to meet set point. |
