Environmental Walk-in Rooms

From small reach-in chambers to a suite of large modular capacity walk-in (or even drive-in) rooms - LTE designs customised solutions in applications where precise environmental control is a prime requirement.

Features include:

• Custom built to your requirements
• Simple to install - simple to relocate
• Modular construction
• Close temperature and humidity control
• Dedicated project management
• Electrical installations comply fully with current IEE regulations
• Full calibration and validation service

Typical applications are:

• Stability testing for pharmaceutical products
• Shelf life experiments in the food industry
• Packaging research and trials
• Bulk cell culture in biotechnology applications
• Large scale incubation
• BOD tests in water analysis
• Plant growth
• Industrial environmental testing applications

Rooms are typically built to operate at temperatures between –30°C and +50°C. Normally our rooms are supplied within accuracy limits of +2°C. However, a special roof plenum and floor ducting system can be incorporated where an enhanced performance of +1°C is required. Humidity is normally controlled within +5%. Where applicable, LTE rooms comply with the climatic simulation requirements laid down in current ICH guidelines

The control systems encompass precise electronic temperature controllers and indicators, over-temperature protection with alarms and other indicators, temperature recorders (optional), interior lighting, occupancy warning light, internal door release mechanism, and an audible occupancy alarm activated by people within the room. Additional control equipment is included to meet particular humidity specifications.

Optional equipment supplied can include:

• Data acquisition systems to record temperature and, if required, humidity information and download it to an intelligent receiver or PC
• De-mineralised water systems where humidity control is required.
• Dual-run/back-up systems which ensure constant running of the rooms, even in the event of routine servicing or maintenance - ideal in long-term test applications.
  

All environmental rooms are built on modular construction principles using panels manufactured from high density polyurethane foam sandwiched within a skin of galvanised sheet steel. The normal finish is white pvc, although stainless steel linings can be incorporated if requested. A range of floor finishes are available - for example, seamless vinyl, galvanised steel, or rigidised aluminium. Rooms may be fitted with shelving manufactured from coated steel, aluminium, stainless steel, or other materials. Electrical fittings, drains, and enhanced lighting are supplied according to specified requirements.

The initial step is for the customer to request us to carry out a site inspection.

The survey is without commitment, following which we will submit our proposal for the most cost-effective solution.
