Engineering Energy – Critical plant monitoring system

Engineering Energy is a Bristol based company which provides 24 hour call out services to its customers, who are predominantly commercial caterers, data centres and restaurants utilising HVAC (heating, ventilation and air-conditioning systems).

In their business, the biggest challenge is caused by breakdown in the customer critical HVAC systems. In a commercial kitchen for example, if the extraction system were to fail the kitchen may need to close entirely until the system was returned to normal operation. This is obviously damaging to the business commercial aspects but also causes Engineering Energy pressure – they need to reinstate operation as quickly as possible in order to reduce the impact on their customer. Even with regular service and preventative maintenance it is not possible to completely eliminate breakdowns.

Managing director of Engineering Energy, Lee Coombes, looked across the market for a solution to this problem and after months of failed research decided to investigate the custom development of a system to analyse and report on the performance of the HVAC systems. He took his design and met with Paul Mullen of Cubik Innovation and over a period of months Cubik manufactured and demonstrated a system which could predict failure of HVAC systems, show when maintenance was required and even show when filters need changing.

In addition to the failure early warning notification, the system will save a considerable amount of energy consumption in HVAC. This has been proven out and savings of 10% should be possible with further development.

Engineering Energy installed the prototype systems onto customer sites to carry out R&D and within a few months had raised early warning of a number of service issues, proving the power of the detection system instantly saving the customer money and a potential closure.

Lee Coombes commented “The solution designed by me and developed by Cubik Innovation has been really successful in field testing. It will save time, save system shutdown or failure but more importantly save money.” Lee said “The development process was very interesting and Cubik captured everything I wanted in the design and manufacture process. Time with Cubik was always useful, informative and unpressured”.

Cubik look forward to the roll out of the product in 2019. We have been selected as the manufacturing partner for the project and look forward to helping Engineering Energy succeed. Paul Mullen, Managing Director of Cubik Innovation commented “This is a classic engineering dream – the customer has highlighted a problem, we have developed a solution and the results can be measured in the real world”.

Cubik look forward to supporting Engineering Energy with ongoing batches of their Critical plant monitoring system into 2019 and beyond.



Adrian Schmieder of HiETA commented: “Cubik’s quick turn-around of a functioning PCB has sped the delivery of the project and enabled me to focus on areas of the project in which HiETA has expertise.  The project is a great success and produced valuable information even from its first use.  I am very impressed with the support Cubik provided me throughout the project, from initial concept through to PCB delivery.  I will not hesitate to engage with them again as future PCB projects arise.”


Speaking about the collaboration between Inductosense and Cubik Innovation, Founder and CTO Dr Chenghuan Zhong (Bamboo) stated: "It was great working with the knowledgeable and experienced team at Cubik Innovation. They always provide full support as well as useful and thoughtful advice to us, helping us find solutions for really difficult problems."


Geoff Jones, Aquabar Inventor: "It was a pleasure to work with Cubik on our project. Paul and Sam understood the concept at one meeting, and produced a solution filling the brief within two weeks which has enabled us to find a potential partner. We will certainly use Cubik for our production units later in the year, Many thanks."

Paul Davey, Associate Professor (SL) Plymouth University: "If you need a prototype developed to a high standard and on time you would be hard pushed to find someone better. They have highly trained, experienced engineers who get the job done."

Clean Energy Prospector Ltd

Damon Rand, Head Product Design: "Paul and the team have really helped us speed up the turnaround on our prototypes and assure the manufacturability of our designs. If you’re designing electronics in the South-West, then Cubik is a great choice for short-run manufacturing."
