Air Conditioning, Refrigeration & Heating Installation
We design and implement air conditioning, refrigeration equipment and heating systems for all environments, from factories and offices to prestigious buildings and mission critical areas. This includes hospitals and laboratories, food manufacturing, restaurants, catering stores, technical and IT equipment areas. Every unit can be manufactured and installed to your exact specifications and layout to maximise efficiency and performance.
Air Conditioning and Heating Installation
We take temperature control seriously and leave nothing to chance so all installations start with a consultation at your premises to establish your unique requirements. Once MGi has a clear understanding of the needs of your particular location, we set about designing a bespoke solution that provides both the layout and functionality required.
Refrigeration Installation
We specialise in the design and installation of modular and bespoke chiller and freezer rooms. Industrial and commercial sizes vary from small reach-in and walk-in rooms to large drive-in rooms. We ensure your refrigeration installation has additional fail safes such as load-sharing backup systems and thermographic recorders so you have an audited record of temperature performance in real time. We cater for completely new systems as well as additions to your current facilities. And if security is important to you, we can install audio and visual alarms with access control systems so that no unauthorised personnel are admitted. In short, our cold rooms and industrial freezers are designed with safety strategies built in.
