Warranty claim Xylem products are high quality products with expected reliable operation and long life. However, should the need for a warranty claim arise, contact your local sales representative or the manufacturer. Product Description GENERAL DESCRIPTION Brazed plate heat exchangers consist of thin corrugated stainless steel plates between a thicker frame plate and pressure plate that are vacuum brazed together to form a durable, integral piece that can withstand both high pressure and temperature.
Installation WARNING: Many heat exchangers circulate fluids which are irritating or dangerous to the human system. These fluids could cause problems if bolted or threaded joints are not maintained in a leak tight condition at operating pressures, temperatures, an no flow, ambient conditions. CAUTION: Even if fluids are not irritating or dangerous, a leak could cause a slippery situation on the floor below. CAUTION: Since one fluid in the heat exchanger is at a higher temperature, any leaks may cause burns.
4. Provide air vent valves for the heat exchanger so that it can be purged to prevent or relieve vapor or gas binding. 5. Install proper relief valves and temperature alarms to insure the heat exchanger isn’t subject to conditions beyond the intended design. 6. Don not weld or braze brackets or attachments directly to body of heat exchanger. 7. For soldering type connections braze with minimum 45% silver solder and at a maximum 1200° F. For welded type connections use TIG or MIG welding. Avoid overheating.
. For units with integral mounting tabs ensure unit is fully supported in place prior to tightening the support tab bolts. Do not use the support tab bolts to pull the unit into position. Ensure the correct number and size of bolts for the unit type is used to bolt the unit into place. Bolt unit into place using the maximum torque values in Table 4. 10. For units supplied with mounting studs use Table 5 for maximum torque values. Damage may occur if studs are over tightened.
Operation WARNING: A heat exchanger is a pressure vessel designed for operation at certain specific limits of pressure and temperature. The cooling or process system, which includes the heat exchanger, must be safeguarded with safety valves and controls so that these heat exchanger design conditions are not exceeded. All operating personnel should be made aware of these specific design pressures and temperatures prior to start-up. 1.
