Eaton Williams have proposed ceasing the manufacture of the Colman and Qualitair product ranges and concentrate on its air handling, humidification, data centre and service offerings.
In light of the changes, its employees based in Stoke-on-Trent, Edenbridge and Oxford will commence a consultation process with the Works Council and union representatives.
A company statement said these discussions could result in a number of redundancies.
Following the acquisition of Reznor LLC in June 2014, parent company Nortek carried out a review of its operations across Europe that principally involved Eaton Williams Group, part of Nortek Air Solutions.
Eaton Williams supply primarily cooling products; while the Reznor LLC Group (AmbiRad UK, Reznor UK, Reznor Europe and Gaz Industrie) supply primarily heating-based products.
There are collaborations between the businesses, both in the markets served and their operations.
Both are focusing on maximising service and improving their ability to deliver value to customers.
Eaton Williams said the restructuring will ensure a stronger, more agile approach through leveraging the combined strengths of the Nortek Global HVAC division in Europe.
