Hurtwood manufacture a range of retrofit controls products for older and obsolete BMS’s. We have developed our flagship Staefa Retrofit product to provide an easy and low cost swap-out route for the old Staefa AS1000 RSM system by replacing the main NRUA/A to NRUD/A controller cards.

This system is flexible and is easy to service and commission.

The Staefa Retrofit 48IO cards plug directly into the housing for the original NRUA/A to NRUD/A Integral RSM series of controllers and have connectors for the ribbon cables of the original NTIM and NTOM modules.  They can read all the pre-existing Staefa sensors.

Staefa Retrofit cards are a powerful and cost effective input/output card and a wide variety of ribbon cable connected input and output modules are available. Variations to suit particular customers’ requirements and to meet any retrofit application can be built on demand. Just get in touch.

Hurtwood also manufacture replacement modules for the NTIM and NTOM racks allowing the Staefa system to be maintained and added to for many decades to come.

Our Staefa retrofit product is retailed directly through Hurtwood or from a series of distributors.  For details, contact us or see the website.
