Page 5: C: Principle Of Operation
C: P RINCIPLE OF PERATION Thank you for purchasing a Baldwin Model 225 Thermo-Electric Cooler. Baldwin’s Thermo-Electric Coolers are specifically designed for high ambient temperature & high water volume applications. Each model features an oversized heat sink and high performance thermoelectric devices for high heat removal capacity. Heat sinks used in Baldwin Thermo-Electric Coolers are made out of high heat transfer extruded aluminum with large 3/4"... - Page 6 When a positive DC voltage is applied to the n-type thermo-electric element, electrons pass from the p- to the n-type thermo-electric element and the cold side temperature will decrease as heat is absorbed. The heat absorption (cooling) is proportional to the current and the number of thermo-electric couples. This heat is transferred to the hot side of the Peltier element where it is dissipated into the heat sink and surrounding environment.
- Page 7 The sample gas is passed to the thermo-electric cooler via the heated filter sample probe and heated sample line. The thermo-electric cooler lowers the sample dew ° ° point to 5 C (41 F). As the gas cools and the moisture vapor condenses, the condensate exits the heat exchanger through the bottom drain connection.

Page 9: E: Start-Up Procedure
E: S TART ROCEDURE When connecting power to the 225 cooler, proper EARTH GROUNDING is essential. Use a 15 amp minimum, three-conductor power cord. Connect the green with yellow stripe conductor (Earthing) to the protective earthing ground lug on the 225 chassis. -
Page 10: F: Led Summary
F: LED S UMMARY The Model 225 has dual-channel front panel indicators with three LED status displays for each active channel (2 green, 1 red per channel). These indicators are arranged horizontally on the front of the cooler on their respective channel sides. °... -
Page 11: G: Setpoints
G: S ETPOINTS A. Set Point and Calibration Potentiometers 1. Disconnect power from the Model 225 Cooler before removing cover. 2. Remove the cover. Remove the Thermocouples from TB 1 and TB 8. The Thermocouple Generator should not be connected to either of the thermocouple inputs at this time. - Page 12 9. Set the Thermocouple Generator to 25o C. The middle left-hand side Green LED, D3, should be ON and the left-hand side LED, D2, should be OFF. 10. Set the Thermocouple Generator to 0o C. The left-hand side LED, D2, should be ON and the middle left-hand side Green LED, D3, should be OFF.

Page 14: I: "New Jersey" Thermocouple Option
I: “N ” T ERSEY HERMOCOUPLE PTION Some air quality management districts (e.g., those in New Jersey and Southern California) require temperature measurement of the gas stream at the outlet of the last heat exchanger on the cooler. Baldwin offers a 1/32-inch diameter hypodermic- style type K thermocouple that can be inserted into a special heat exchanger (i.e., it has a small port for insertion of the thermocouple) so the actual sample dew point temperature can be measured. -
