We are pleased to provide you with below information on our Principals’ Messrs. AMOT – CHALWYN, affiliated companies and world leaders in the field of Temperature Control and Diesel Engines Safety.

AMOT is a world leading designer and manufacturer of energy control valves, safety, and monitoring products for engines, compressors, turbines, and other rotating equipment.
AMOT has been established as the only company in the world that offers a wide range of products for each one of these applications.

Thermostatic control valves can be easily installed and require minimum maintenance, which ensures high performance during critical applications.
Especially, in situations where temperature fluctuations require flexible temperature adjustment, AMOT Model G Valves is the optimum choice. AMOT G valves can increase output and decrease warm up time by providing tight temperature control.

3-Way Temperature Control Valves, AMOT’s 3-way temperature control valves, improve the efficiency and modernize the performance of natural gas and diesel engines by controlling the temperature of vital engine fluids.
The pneumatic G Valve system is ideal for cases where there is a lack of electricity or when installation is needed in a hazardous area.
The electro-pneumatic system combines the features and functionality of the AMOT electronic control system with the fail-safe action benefits of a pneumatically-actuated valve.

CHALWYN is the global leader in the manufacture of air intake shut down valves, ensuring the control of Ignition Sources from Diesel Engines and eliminating the risks in Sensitive/ATEX areas.

Air Intake Shutoff Valves, (often referred to as AISV, ASOV or Emergency Shutdown valves, ESD) and relevant systems provide emergency overspeed shutdown protection for diesel engines and are the most effective way of preventing a runaway situation.
The valves completely block the engine air intake system, cutting off an uncontrolled external fuel source and the air required to keep the engine running.
Manual, Electric, Automatic and Oil/Air Pressure, overspeed protection for your Engines, a Safety Practice that has been established by all major Oil & Gas Companies in the Gulf, implemented in their HSE Regulations.

Spark Arrestors

Diesel Engine exhaust spark arrestors are a basic but key safety feature for both hazardous areas and lower risk diesel engine applications such as forestry or agriculture where a stray spark may cause ignition of combustible material.
Their importance is apparent also due to the existing regulations regarding the operation of a diesel engine in a hazardous area as they include mandatory requirements to fit a tested and approved exhaust spark arrestor.

TECHNAVA SA, continues to invest in new products, technologies and solutions to meet the evolving needs of modern engines with increasing performance standards.
