DEHUMIDIFIER MODEL D 700

Introduction

The vast majority of natural substances (except the exceptional ones), especially various metals, damaged, more or less, by dampness.

The phenomenon is known and virtually anyone can see during time rusty tin or rotten wood as a result of contact with water.

To avoid these undesirable effects of the stored equipment, optimized removal of the moisture in the air. There refrain from producing complete dryness, which causes a lot of damage as well, especially cracks and blasting parts made from plastic and rubber, thus drying it up a optimal level.

Principle of Operation

Removing water from the air is carried out with a dehumidifier which imitates the natural phenomenon of dew. The principle of operation of the dehumidifier is based on a cooling system which cools the air flowing through the dehumidifier to the point where dew falls from the air. Dew drops drain out of the system, and the cold air and dry air passes through the hot zone and is emitted to the dehumidifier.

Temperature of outgoing air from the dehumidifier is only slightly higher temperatures incoming air.

The dryer is able to work in the field at temperatures around 5° C to 55° C +

The problem of water stagnation inside the dryer temperature to below - 12° C is solved using a defrosting system that operates only when needed and melting the ice.

Description of Dehumidifier

Compressor - Its role is to suck refrigerant gas from the evaporator and compress it into the condenser part.

Condenser - Serves as a heat exchanger which cools the gas and change accumulative status from gas to liquid.

Evaporator - Also serves as a heat exchanger, but unlike the condenser, the fluid becomes a gas.

Fan- To spin the air in a way that will work through the evaporator, and move between the cool ribs of the condenser.

Humidity regulator– The function is to measure the relative humidity and supervise the operation of the compressor.

Base - It consist of all dehumidifier components and used as a drainage tray to remove the water.

Housing - Used as a cover for the dehumidifier and directs air flow through the dehumidifier, attaches handles for easy carrying.
