Performance |
With High Efficency of Heat Transfer. Compact structure, surface area can be 1000~2500m/m because of expansion of plate-fin heat exchanger with the quadratic surface Well adapted, Plate-fin heat exchanger can be applied to: gas - gas, gas-liquid and liquid-liquid. Pressure Strength Resistant Capability is high.(Max 4.0Mpa) Low temperature resistant capability is strong(Ambient Tem.-65°C) Fin lodging resistance capability is strong, easy to maintain, flush. |
Installation
Be careful when lifting off , forbidden knock against.
To fix the heat exchanger on the base by installed hole, are not allowed to shake.
To guarantee fan installation and fan cover to be concentric, pay attention to suction and blowing.
Motor wiring in accordance with motor manual, pay attention to motor veer.
Tube connected to the system may not be misplaced, twisted, no to be leakage.
Not allowed to have obstruction in front and back of heat exchanger.
Internal medium in heat exchanger should be kept clean, no granular, floc impurities.
Outside air of heat exchanger should be maintained no weeds, batting, dust, particles, to avoid blocking.
During running, if appear much noise and resonance phenomenon, stop immediately and check.
Maintenance
Regularly check internal medium quality of heat exchanger, if there is particles, floc matter etc, need exchange in time.
If heat transfer performance fall largely, please stop and check.
The vibration of equipment during the operation may cause connection bolt loose. Therefore, the connection position should be checked every three months.
The equipment must be operated under design pressure, overpressure operation is forbidden.
