Condensing Unit - Immunity from Vibrations

  1. Sufficient consideration in design must be given so that mounting parts and connected parts are not damaged as a result of vibration or shock sustained while transporting the fully assembled equipment. It should be confirmed no damage by the transporting test.
  2. The systems must be sized for max. 80% of standard compressor operation. 100% compressor operation only occurs in special overload and ambient temperature conditions that are outside of the normal permitted operating limits.
  3. The system has to be sized as not to have more than 5 ON/OFF cycles per hour. The intervention of thermal protection device switches off the compressor, which will be started again after the time required for the protection device contacts to be connected.
  4. In the machines fitted a dual pressure switch set to the following values:

‍Set Bar: HP 27 / LP 1

Difference Bar: HP 4 / LP 1‍

Pressure switch for Pump-down: this must be set considering that the compressor must not startup at intervals that are too close together (5 minutes at least). In these cases, we recommend the use of a timer for the compressor start delay.
