What EJM Engineered Systems does
EJM Engineered Systems Limited is a UK-based independent refrigeration contracting company founded in 1980 and headquartered in Shotton Colliery, Durham, with a second office in Stockton-on-Tees. The firm designs, installs, commissions, and maintains industrial and commercial refrigeration systems, with particular specialisation in natural-refrigerant technologies including ammonia (NH3) and transcritical CO2, alongside pre-insulated pipework, VSD compressors, EC fans, RDM-integrated controls, and IceDry desiccant dehumidification. Its service portfolio spans industrial refrigeration, commercial refrigeration, air conditioning and ventilation, and ongoing service and maintenance, supported by the proprietary CLIK asset-and-compliance tracking tool.
The company serves enterprise clients primarily in food processing, cold-chain logistics, and adjacent regulated sectors such as pharmaceuticals, healthcare, and laboratories. Documented customers include Whitby Seafoods, Reed Boardall Group (a 140,000+ pallet cold storage programme), Langdon Industries / The Nagel Group, and JJL Design & Build for regional distribution centres, with project scales reaching 1150kW frozen-store and 872kW chill-store duties. EJM holds EN ISO 9001:2015, PED 2014/68/EU, Safe Contractor, NEBOSH, and Refcom F-Gas certifications, and operates a direct field-sales GTM with quote-based, multi-year project and maintenance contracts across the UK.
Revenue is generated through one-time installation projects (industrial and commercial refrigeration, AC and ventilation), recurring service and maintenance contracts (planned visits, emergency call-out, leak detection, remote monitoring, compressor overhauls), and professional-services work such as on-site compressor rebuilds. The business is privately held with no disclosed investors, parent company, or external funding, and EJM emphasises its manufacturer independence as a procurement and design flexibility advantage.

EJM Engineered Systems competitors and assessment
Company assessmentBroad incumbents
- Johnson Controls: Global HVAC and building controls incumbent offering industrial refrigeration, cooling and integrated facility services. Competes with EJM at the enterprise level for large multi-site service contracts, though not specialised in UK ammonia/CO2 industrial refrigeration.
- Bitzer: Leading global compressor manufacturer whose equipment EJM services and installs. Bitzer competes indirectly via its certified service partner network and direct end-customer relationships in industrial refrigeration.
- Carrier: Global refrigeration and HVAC OEM and service provider with significant UK industrial and commercial refrigeration presence. EJM services Carrier equipment and competes with Carrier-affiliated contractors for installation and aftermarket work.
- Trane: Global HVAC and commercial refrigeration OEM offering design, installation and service across commercial and industrial customers. Overlaps with EJM in air conditioning and commercial refrigeration, particularly for office, retail and light-industrial projects.
- GEA Group: Global manufacturer of industrial refrigeration compressors and systems (including Grasso) and an EPC contractor in cold chain. EJM specifies GEA/Grasso compressors in its projects, so GEA competes both as a supplier partner and a broad incumbent serving overlapping end markets.
Direct peers
- Star Refrigeration: The largest independent industrial refrigeration contractor in the UK, offering ammonia and CO2 system design, installation and service across food, cold storage and industrial customers. Directly comparable to EJM in core services and customer base, but at materially larger scale.
- Carter Synergy: UK refrigeration and air conditioning contractor delivering industrial and commercial projects with a focus on energy efficiency and natural refrigerants. Comparable independent UK contractor competing for similar food-industry and cold-storage work.
- Cooltech (Cool-Tec UK): UK commercial and industrial refrigeration contractor providing installation, service and maintenance across the food retail, cold chain and HVAC sectors. Closely comparable mid-sized UK contractor serving similar enterprise customers.
- Pro Refrigeration: Independent UK refrigeration contractor providing design, installation, service and maintenance for commercial and industrial clients, including food processing and cold storage. Directly comparable offering and customer profile.
Emerging players
- FrigorTec: European specialist in industrial refrigeration and compressor technology focused on natural refrigerants and energy efficiency. Adjacent specialist competitor with overlapping technology focus (ammonia/CO2), particularly relevant in food and cold-storage applications.
