1. Why should you use Enclosure Cooling Unit


Fig. 1 Showing pollution in normal factories


In a factory, without a good ventilation serious hazard could occur. Whether it may be a packing machine, forklift, crates, paint machine, or pressing machine seen in Fig.1. Dust, smoke, heat, or chemical could cause damage to machine and worker's health.

There are 4 different ways to cool down your machines; fan type, heat exchanger type, air-condition type, and enclosure cooling unit type.


There are 4 main factors we consider when measure the ability and efficiency of cooling equipment.


The solution for dispersing heat from electrical control units

should be considered from multiple factors such as

environmental and ambient temperature of control cabinet,

size of the control cabinet, power of electric device in control cabinet, surrounding area,

energy consumption of each the thermal variations and more.

Heat exchanger

The method of heat dispersion has gained high popularity abroad because of costs that are lower than air-conditioning. However , the user of this method is ineffective when used in countries with hot climate due to its mechanism as outside temperature must be lower than the control unit's temperature to soak up the heat and reduce the unit's temperature.

Vortex tube

An air pump is used to generate air current which is directed through piping that leads to various points of use. When many points are using the force created by the air pump , the actual force at each destination is divided and lessened causing drop in efficiency of heat dispersion and the benefits are typically outweighed by the cost.


The method is rather high in terms of costs. It requires building a surround for the control unit to contain the coolness and installing the air-condition unit which wastes a lot of space. The heat accumulated within the control unit will have no outlet. Fixing this problem by installing a fan to the control unit to draw cool air leads to higher costs and the possibility of contaminants being introduced into the control unit which lead to increased maintenance and repair in long-term. Also , employee health can deteriorate from working in this rooms that carry the smell of electrical equipment and electronics equipment.


It functions with little complexity by installing a fan on the side of the control unit to draw in air from the outside to reduce heat within the unit to prevent accumulation of heat. The amount of heat reduced within the control unit is mainly dependent upon adjacent temperatures. This method uses an open system which can introduce contaminants and humidity into your control unit which will surely lead to no benefits.

Cooling Unit

We have the best fitting and best value aid in dispersing heat from electrical control units and electronics. We call Cooling unit or the another name of that is Enclosure Cooling Unit , Control Temperature Unit , Panel Cooler , Panel Cooling Unit etc.


This is an outstanding solution to solving the issue of heat retention within a control unit and it can also prevent humidity and contaminants (which can cause damage to components and equipment within the unit) better than other methods.


It works as a closed system that generates coolness within a component that supplies cold air inside the control unit to disperse heat. The heat is drawn into an air duct to be distributed to the outside.


One just needs to install the component to an opening cut into the control cabinet and seal the control cabinet to create a boundary for maintaining coolness within.

 The conclusion is that it is very important to consider many factors in selection the best value between the different methods of heat dispersion before making an investment.
2. Why should you use Dindan's services

Attention in designing the cooling unit to achieve its high performance, we have continuously researched and developed every engineering aspects numerically.

With compromise to easy-operating designed then DINDAN™ obtain its outstanding identity.

Careful with condensation


Drainage of condensation is the most hazardous to those machines installed cooling unit

Hi-prosent control


The controller is functionful with the protective of every failure of system

Aerodynamic for ventilation


Air flow and its pressure are fully considered with its flow impedance in order to maximise its ventilation performance then cooling performance obtained.


Computational design for heat exchanger


After simply dimension for the heat exchanger is outlined. Heat transfering in condenser and evaporater are initiated by computation method for consider the stability of the heat exchanging in various ambient conditions with refrigerant property.

Thermodynamic Examination


In order to obtain proper designed condition of cooling system we monitor every thermodynamic quantity with our special software. Over high pressure abovecompressure shorten it operating life. Balancing between high pressure and low pressure is the factor for cooling performance.
