Company Description

Hurtwood are specialists  in cost effective BMS upgrade strategies that provide you, the client, with far more monitoring, control and energy savings than were possible with older systems. We take a holistic approach to all your control equipment including statuatory monitoring requirements such as fire dampers and legionella control and how your BMS can improve these.  We also assist clients to upgrade their older BMS and process control systems to the modern equivalents by manufacturing an innovative range of retrofit controls products. Hurtwood also offers wider plant consultancy and engineering services that can deliver energy savings, improved control and low cost supplies of heat for industrial processes, commercial and public sector energy users.  Our experience is broad but we are highly specialised in the acute healthcare and commercial office sectors.

Our flagship product is the Satrofit range of input and output cards and terminal unit controllers that provide an easy upgrade route for older Satchwell, Staefa and Sauter BMS equipment to a system of your choice.  Satrofit is also a powerful IO system that allows a non BMS trained engineer to fully commission the field sensors and outputs prior to integration into a larger BMS.  Find out more or visit
Our flagship consultancy  service is the review and re-engineering of a wide variety of building controls and Building Management Systems (BMS) that can achieve typically 10-15% energy savings for low capital cost, paybacks often falling within a year, sometimes less.
Hurtwood also has a wealth of experience on industrial heat supply systems including steam and high temperature hot water, steam boiler plant and the industrial combustion of coal and wood.

Some interesting projects completed recently:

Bristol Office BMS refurbishment

Starting June 2013, this project involved the refurbishment of an obsolete AS1000 BMS to a modern Siemens Desigo BMS using our Modbus retrofit product. The entire upgrade of over 500 points was carried out for £35,000, a highly cost effective upgrade.

A Major South London University Hospital

The refurbishment of the motor and environmental controls on the London Wing was the first successful application of the retrofit concept.  CUH had an old Honeywell Excel Classic system which we wanted to upgrade to Trend.  We manufactured a simple PCB upon which 2 Trend IQ3 modules were mounted.  These PCBs, equipped with the original Honeywell 31 pin connectors, plugged straight into the old Honeywell Back-planes.  As a result, we were able to refurbish the entire London Wing controls, approximately 450 points, during a couple of weeks over a summer shutdown of the operating theatres. At the same time, we put in EP converters and eliminated all the old pneumatic temperature controls.  The Trust recieved a new BMS which they didn't believe they would get with the finance and the time they had available.

A Major City Council

Researching and publishing a strategy for the migration of their controls from a Satchwell Sigma BMS to a Siemens Desigo BMS allowing the integration of far more of the councils monitoring and control services onto the BMS as well as achieving a step change in the effectiveness of their BMS maintenance. This covered a wide range of buildings from heating only boiler plants through to deep plan office buildings with Variable Air Volume (VAV) air handling systems. The predicted energy savings calculated by Hurtwood delivered the Salix funding that allowed the project to go ahead.
