Our range of innovative solutions support fault-free operation for defence equipment deployed in wide range of harsh and unpredictable environments, from applications deployed in humid regions with large temperature fluctuations and excessive moisture to high-altitude and underwater instruments that are subject to rapid pressure variations and immersion. Our range spans from DEF-STAN desiccant bags and NATO-approved nitrogen purging equipment to ultra-clean desiccators and desiccant sachets, and a wide range of panel-mounted solutions to protect, including high-flow pressure relief valves, document & desiccant ports and electronic humidity indicators. We have a long-standing history with the security and defence industry; providing both custom and off-the-shelf solutions for the protection, control, and measurement of high humidity and moisture, vacuum and pressure variations, immersion, corrosion and more
Sea
Protect naval electronics, weapon systems, and sealed compartments from salt-laden moisture, humidity, and corrosion, extending service life and ensuring mission capability in marine environments.
Land
Prevent moisture ingress, corrosion, and dust damage in vehicles, weapon systems, and communications equipment, maintaining operational readiness in harsh environments.
Air
Safeguard avionics, sensors, and mission-critical systems in aircraft from condensation, pressure changes, and particulate contamination, improving performance and reducing maintenance.
Space
Protect sensitive satellite and spacecraft components from moisture, outgassing, and particulate contamination during storage, transport, and operation, ensuring long-term reliability in vacuum and temperature extremes.
Relevant Solutions
Custom Desiccators
Our problem-solving capabilities - built from over 70 years of research and experience - along with modern in-house manufacturing and testing facilities allows us to design and build tailored desiccators to fulfil specific requirements
Document Ports
A wide range of panel-mounted document ports, offering secure storage of important records and reports; allowing for easy access whilst protecting contents from exposure to extreme and rapidly changing environmental conditions
DEF-STAN Sachets
Specialist defence standard desiccant bags, produced and tested to MOD DEF-STAN 81-61/5 and DOD MIL-D-3464E, and crafted for the protection of military applications including optical equipment, weapons systems, and sensitive electronics
Ultra-clean Bags
Ideal for applications with limited space that require a desiccant with high dust attrition resistance, our ultra-clean bags are with molecular sieve desiccant and offer particle filtration down to 0.2 microns. Available in 2g to 30g sachets
High-flow Relief Valves
Solutions intended for applications that require the moving of large amounts of air in short periods of time, automatically. Our High-flow relief valves offer both pressure and vacuum relief for rapid or explosive decompression
Electronic Humidity Indicators
Monitor relative humidity, ambient temperature, and dewpoint levels in real time with high accuracy with our ERHIs. These robust, and easy-to-install units are rated to IP67 and feature an LED display and 5-year+ battery life
Typical Applications
Equipment Containers
Our solutions are designed to control the internal conditions of Military Containers in extreme or rapidly changing of environments, helping to maintain functionality and integrity of the critical materials and equipment within
Missile Systems & Seekers
From Ultra-clean Desiccators and Desiccant Bags to specialist Purging Equipment, we offer ultimate protection for the missile seeker, body and the container, ensuring optimal performance and fault-free operation during all stages
Night Vision Instruments
Night Vision Devices & Thermal Imaging Equipment play a critical role in Security & Defence operations and must be protected from extreme conditions such as shock & vibration, pressure & temperature variations, and high humidity
Purging Equipment
Our NATO-approved NEPS 1000 range - available in a range of practical configurations – has been in the market for over 20 years and is designed to eliminate moisture from a wide range of defence equipment including electronics, optics, and electro-optical instruments - ensuring optimal performance and longevity while reducing overall equipment obsolescence. The NEPS², an extension of the NEPS1000 range, is a robust and responsive system that features adjustable software settings, an intuitive user interface, and durable 7-inch touchscreen. New functions include built-in data logging, enhanced leak testing and optional vacuum purging
