Page 63: Chapter 7 - Frequently Asked Questions
How can I modify the chamber to cool faster or colder? Unfortunately, there is nothing you can do to improve upon the designed-in performance. TestEquity does NOT recommend using CO or LN in this chamber to achieve colder or faster cooling due to reliability and safety considerations, so it is NOT an available option. - Page 64 This will ensure that nothing has been damaged and that a leak has not developed. Can/Should I put a filter in front of the condenser air inlet? No, TestEquity does not recommend this. Just follow the maintenance procedures and clean the condenser fins periodically.
-
Page 65: Chapter 8 - Specifications
Operation at higher ambient temperatures will result in decreased cooling performance. Low end limit derates to -38°C when operating above 27°C (80°F) ambient. Operation above 30°C (85°F) or below 16°C (60°F) ambient is not recommended. TestEquity 155 Temperature Chamber Page 65... -
Page 67: Chapter 9 - Maintenance
• Listen for abnormal noise or vibration. Every 6 Months • Inspect the door seal. • Clean the condenser. • Inspect the electrical/refrigeration compartment. • Verify the chamber performance. Every 12 Months • Verify the calibration. TestEquity 155 Temperature Chamber Page 67... -
Page 68: How To Clean The Chamber Interior And Exterior

4. Inspect for oil around refrigeration valves, fittings and joints. This may be a sign of leaks. 5. Inspect for loose hardware and tighten as required. 6. Check for loose wires and burned insulation near terminals. 7. Inspect for signs of insect or rodent infestation. Yes, it does happen! TestEquity 155 Temperature Chamber Page 69... -
Page 70: How To Verify The Chamber Performance
Temperature Controller’s setup and tuning values have not been changed from the values as shipped from TestEquity. Also, the Limit Controller high limit must be set to over +85°C (+100°C would be fine), and the low limit set to –27°C. If the chamber fails any of these tests, it should be removed from service to prevent further damage until the cause of the problem is determined and resolved. -
Page 71: How To Verify The Calibration
TestEquity recommends verifying the calibration before attempting to actually perform a calibration. The microprocessor-based instrumentation used in TestEquity chambers seldom goes out of calibration. If you try to calibrate the instrumentation before determining that calibration is necessary, you may make it worse if done incorrectly. -
