Understanding the way in which a system is engineered, and the basis on which components are selected for each type of equipment, can be useful when deciding on the options for your application
The refrigerants that are commonly used in refrigeration and air conditioning have changed over recent years, and are still changing, as the drive for greater efficiency and improved sustainability continues.
Selecting the most appropriate refrigerant is an important choice

As with the refrigerant, compressor choice determines many of the characteristics of the unit in which they are installed.
What are the features of each type of compressor and what are factors to consider when deciding on the best solution for your cooling requirements?

The evaporator is one of the most important components of a chiller, and its purpose of is to transfer the cooling energy from cold gas of the refrigerant to the water or other coolant media.
Two of the three commonly used types of evaporators are found within Petra's range of chillers
In modern chillers and AC systems, we principally find that two of the four types of expansion device to be most frequently used are the thermostatic expansion valve and the electronic expansion valve.
Details of the function of the device, the differences between the types and the benefits of each can be found here...
The modern day drive for energy savings in buildings has resulted in buildings with small openings and little natural ventilation. Consequently, energy saving goals and environmental comfort conditions can be in conflict, making an accurate and responsive controls system a vital componenent
