We design, build and commission environmental simulation systems for Defence, Aerospace, Space and critical industries. Over 600 chambers delivered to ISRO, DRDO, HAL and more since 1995.
Founded in 1995 as Clitec Engineers and now operating as Envirotec Engineers (India) Pvt. Ltd., we have spent three decades at the forefront of environmental test chamber design and manufacturing in India.
From our 2,000 m² facility in Hyderabad, we engineer, fabricate, install and commission complete environmental test systems that replicate the harshest conditions on Earth and beyond.
We manufacture all types of environmental test facilities to qualify products Made in India, championing indigenisation and engineering self-reliance.
Our environmental test chambers qualify critical hardware across India's most vital industries, from missile systems to satellite components.
Qualifying missile systems, warheads, avionics, and battlefield electronics for DRDO, BDL, and the Indian Armed Forces.
Environmental qualification of satellite subsystems, launch vehicle components, and payloads for India's space programme.
Testing airframe components, landing gear systems, and flight electronics for civil and military aviation programmes.
Qualifying transformers, switchgear, solar panels, and battery systems for India's power generation and distribution sector.
HAST testing, burn-in qualification, and reliability screening for electronic components and microelectronic systems.
Battery thermal management testing, EV component qualification, and automotive environmental stress screening.
Precision-engineered test chambers across 25+ models. Each system is designed, fabricated, installed and commissioned in-house, with full compliance to international testing standards.

We have delivered environmental test systems for some of India's most classified and high-stakes defence and space programmes.
DRDO
Engineered a 10-metre fully automated environmental test chamber for strategic missile qualification. The system features remote sequential door operation controllable from 200 metres, a first-of-its-kind capability in the Indian defence programme.
ISRO
Reconstructed a non-functional thermal humidity chamber at India's primary launch complex, cutting replacement cost by 85%. The chamber has been operational since March 2000 with zero downtime.
DRDL
Manufactured a 12-metre walk-in environmental chamber with four 3-metre doors, equipped with a PC-based controller for continuous unattended operation.
ASL / HEMRL
Designed a specialised mobile environmental chamber mounted on dynamounts with integrated generator changeover for field deployment. Proven reliability led to repeat orders from HEMRL, Pune.
HEMRL Pune
Collaborative engineering of frames, casings and full qualification testing for ballistic evaluation motors, a critical link in India's indigenous propulsion development.
