Product Profile of Heat Exchanger
V-Tech Industries is manufacturing Heat Exchanger, under the model name API PLAN 23. The Heat Exchanger prevents product flashing through enhanced cooling. This flush plan is most commonly seen in boiler feed water service. It is essentially a closed loop system; virtually the same product is repeatedly circulated between the seal and the heat exchanger.
V-Tech Industries, an ISO 9001:2008 registered organization offers a range of heat exchangers like industrial water coolers, hydraulic oil coolers, stainless steel heat exchangers, industrial stainless steel heat exchangers, tube heat exchangers, tube type heat exchangers, water coolers, etc.
Key Features of Heat Exchanger
- The heat exchanger should be located as close to the seal as possible with a maximum distance of 3 feet.
- The bottom of the heat exchanger should be approximately 12 inches above the shaft centerline.
- Avoid sharp elbows or bends in the tubing. Use as gentle a sweep in the turns and always have an upward slope from the seal to the exchanger to avoid vapor locking.
- There must be sufficient shaft surface speed for the pumping ring to be effective.
- If possible, use .500" to .750", stainless steel tubing from the exchanger supplying cooled fluid to the seal. Tubing from the seal back to the exchanger can be .375" for 2" shafts and smaller. Use .500" for shaft sizes above 2".
- Always slope horizontal runs of tubing slightly upward [1 to 5 degrees] from the seal to the exchanger to prevent low spots in the line where air can be trapped and vapor lock the system preventing flow.
- Any valves used in the closed loop should be of the free flowing type.
- Whenever possible, locate the pumping ring in the gland where tangential port approaches can be utilized and clearances can be more clearly controlled.
