Introducing Custom Environmental Test Chambers
Bespoke Environmental Chambers Designed Around Your Requirements
Our bespoke chamber service helps organisations create temperature-controlled environments that meet precise testing, storage and research requirements. Working with leading chamber manufacturers and our in-house temperature and humidity specialists, we design custom environmental test chambers, walk-in climate chambers and purpose-built cold rooms tailored to your application.
Whether you’re optimising testing capacity, increasing storage volume or accommodating specialist equipment, every solution is designed around your process rather than forcing your process to fit a standard chamber.


A Collaborative Design Process
Every project begins with understanding your operational requirements, facility constraints and long-term objectives.
Our team provides independent advice throughout the planning, design and specification process, helping you select the right chamber configuration, environmental controls and monitoring systems for your application.
From initial concept through installation and validation, we work alongside you to deliver a bespoke chamber solution that supports your current requirements while allowing for future growth.

Tailored equipment choices
Illumination requirements (e.g. lights for plant growth etc)
Sizing and dimension flexibility
Litre capacity to suit your needs – volume and dimension on demand
Suitability for samples at different test stages
Chamber Types

Walk-In Chambers
Large-scale environmental chambers for temperature and humidity control, including climate chambers, stability chambers, cold rooms and walk-in freezers. Designed to meet your space, capacity and application requirements.

Ultra-Low Environmental Chambers
Specialist ultra-low temperature chambers designed for applications requiring exceptional temperature stability and control. Suitable for long-term storage, research and critical testing environments.

Environmental Test Chambers
Cabinet and bespoke environmental test chambers for simulating temperature, humidity and other environmental conditions. Ideal for product testing, validation and performance evaluation, with calibration support available.
Benefits of custom walk-in chambers
Space optimisation in your custom environmental test chamber
Space optimisation and maximisation
A chamber can be built to fit within your facilities, where we work closely with you to maximise the storage capacity available per square foot.
Special features
Not every chamber on the market will have industry-specific features, with a custom environmental test chamber you can incorporate those crucial regulatory requirements at the initial CAD drawing stage.
Data integration
We can work alongside your continuous monitoring solution or embed a new system for you at the point of design. Data can be seamlessly built in rather than integrated after installation.
Future-proofing
We’ll address your current and future needs, producing an adaptable walk in climate chamber that can be modified and upgraded simply, in years to come.
Custom Chamber Case Studies
Every bespoke chamber is designed around a customer’s unique application, facility and operational requirements. From pharmaceutical stability studies to automated testing systems, our solutions help organisations optimise testing, storage and process performance across a wide range of industries.
