Crabtree Engineering Software develops software for use in the Building Services industry.

The Principal of the company is Andrew Crabtree, a Chartered Professional Engineer with a Masters degree in Mechanical Sciences from Cambridge University. He has worked in the building services industry for over 45 years in the areas of consulting, contracting, commissioning, software development and Commissioning Management.

Our current software products include the following:

CoilPac is a rating and selection tool for HVAC cooling and heating coils. It is designed to be used by system designers, equipment manufacturers and coil manufacturers. It is also available as a DLL for use with 3rd party software and is used by many air handling unit manufacturers.

iSynapse is a building services analytical tool which remotely extracts data from the BMS and/or lighting control systems in a building, reports on  performance, analyses the causes of potential problems and identifies opportunities for performance improvement. This was developed after many years working in the Commissioning Management and Building Tuning areas to enable thorough analysis and troubleshooting of building services in all commissioning, building tuning and operation stages of development. If iSynapse is installed and set up prior to handover of a building there is no reason why any defective systems or equipment should remain undetected and unresolved during the Building Tuning phase.
