  1. Hermetic, Semi- Hermetic and Open Compressors

  2. A compressor is a device used to increase pressure on air by reducing its volume. It is usually done by forcing the air into a closed container limiting its volume and then compressing it with great pressure. Hence formed compressed air has many application values in this industrial era. The two basic components of a compressor would be; the compressor and its driving motor. Depending on the position where the compressor and motor are situated in relation to the air being compressed, the compressors are divided into three:

  3. Hermetic Compressor: These types of compressors are industrially known as ‘hermetically sealed compressors’, because in this the motor and the compressor are sealed within welded steel. Thus, they stay together as a single compact unit, easily maintainable and it prevents any forms of leakage. One major drawback is that they cannot be repaired. Thus if damaged, the only option would be to replace it with a new unit. Semi-Hermetic Compressor: Here the compressors are also enclosed with the driving motor in a common housing. But the casing is with darted type gasketed covers with screws. Thus, the metal casing can be opened at any time without any effort to be repaired. These types are leak-proof and cost-efficient with more life span.

  4. Open Compressor: Unlike hermetic and semi-hermetic compressors, open compressors are more vulnerable to leakage. In these, the compressor and the motor are positioned as two separate units with individual sealing yet they are attached by a belt or crankshaft. The leakage problems totally depend on the quality of the shaft seals. Open compressors are easily serviceable and are cheap as well. The advantage of repairability makes semi-hermetic and open compressors more preferable than hermetic compressors. Overhauling compressor services in UAE provides the best quality maintenance services for both semi-hermetic and open compressors. The damaged compressors could also be restored completely, the qualified technicians of remanufactured compressor services in Sharjah, offer these restoring services with refined quality. 08
