A Harmer Modular 135 linear drainage system from Alumasc has been installed at a major laboratory expansion in Warrington.
The project was delivered by principal contractor Triune Construction, on behalf of global life-sciences company Thermo Fisher Scientific and forms part of ongoing investment at the Warrington facility.
Triune Construction required a stainless steel linear drainage channel system that could meet both performance and hygiene requirements for their client, while also being available quickly to meet the tight project deadlines.

Triune submitted technical drawings to Alumasc, who recommended the Harmer Modular 135 stainless steel drainage channel system. Alumasc’s Harmer team visited site to discuss the specific design and performance requirements in detail, ensuring the system would integrate seamlessly into the laboratory layout.
Harmer Modular 135 is a high-performance stainless steel linear drainage system designed to meet the demands of busy and challenging environments. Constructed from durable, corrosion-resistant 304 stainless steel as standard – with 316 available to order – the system is A1 fire-rated and offers exceptional strength, hygiene and longevity.
The system also had to accommodate a drainage run that discharged directly into a sump at the end of the channel. This was addressed by Harmer Modular’s open-end channel and flange plate detail, which extends beyond the bottom of the channel, allowing the system to feed directly into the open sump, eliminating the need for additional complex connections.
Designed and manufactured in the UK, Harmer Modular 135 is stocked for next day delivery.
Harmer Building Drainage sits under the AWMS umbrella together with Alumasc Rainwater Gutters & Downpipes; Skyline Architectural Aluminium; Wade Building Drainage; and Gatic Civil Drainage & Access Covers. All five brands are well known for innovation, quality and longevity.
