Welcome to Petra UK's New Website
The purpose of this website is not only to introduce you to our HVAC systems, though of course we hope that you will want to discuss your Chiller, AHU, CRAC etc. requirements with us, but perhaps equally important to us is our wish that you will engage with us as we bring all that Petra Engineering Co. has to offer to the UK market.
We are at the very early stages of this mission, and we would sincerely welcome your feedback and support as we continue to develop our business and advance the range of products that we will have to offer.
We hope that within these pages you will find interesting and informative articles and news items, and that you will share your ideas and opinions with us. We will post regularly about our activities in the UK and Europe as well as bring you news about product developments, not only by Petra Engineering, but also from other manufacturers across the globe.
Everyone at Petra, both in the UK, Europe and Jordan, is absolutely committed to succeeding in this venture and we invite you to check into this website from time to time, read our News and Knowledgebase articles (or subscribe to be notified when a new item is published), and let us know what you think.
There are many well known and well established chiller and HVAC manufacturers in the industry today, but our goal is to offer our clients a service that is more personal, more collaborative and gives outstanding value.
Petra UK Team
Petra have been designing and manufacturing HVAC systems for more than 30 years. Our success is built on a solid understanding of engineering and a commitment to building quality products that are robust, reliable and efficient.
The components that are used in each unit are carefully selected for every application. This is what makes the difference. Our philosophy is that as buyers and specifiers of chillers and other HVAC systems, knowing what the options are and how they function together is important for our clients, and enables us to collaboratively create the best solution for every 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
