COLD-ROLLED STEEL

Thermex BIO Series inner tanks are crafted from the finest cold-rolled steel, offering superior durability and adaptability compared to hot-rolled steel used by other leading water heater brands.

The smooth steel surface enhances the adhesion of protective coatings, preventing microcracking and ensuring long-lasting performance.

COLD-ROLLED STEEL
OXYGEN FREE SYSTEM

Exclusive Bio-Glass lined coating technology under inert gas conditions.

The Oxygen Free System eliminates air entrapment and ensures the safety of the inner tank for its entire service life.

Thermex uses advanced ultrasonic scanning for quality control of the protective coating, which detects even the smallest invisible defects in the inner tank with a 100% guarantee, ensuring the highest level of quality.

OXYGEN FREE SYSTEM
PRODUCTION AUTOMATION

The high level of automation at the factory exemplifies cutting-edge manufacturing efficiency, with over 90% of the production process relying on advanced machinery and robotics. This streamlined approach allows the facility to produce a water heater every 15 seconds, translating to approximately 240 units per hour.

PRODUCTION AUTOMATION
ASTN+

Thermex uses a special non-corrosive stainless steel in its inner tanks. Unlike other steels, this high-alloyed steel doesn't rust even under high pressure and frequent temperature changes, which are normal for water heaters.

ASTN+
COLD METAL TRANSFER

C.M.T. is a modern cold welding technology that creates reliable seam welds. It operates at a lower temperature than common welding, preventing the burning of alloying additives. This preserves the metal's structure, resulting in corrosion-resistant weld joints.

COLD METAL TRANSFER
TIG-TRONIC

The automated robotic welding process eliminates the potential for inhomogeneous welds and metal overheating. The high-pressure calibration ensures precision and durability.


TIG-TRONIC
GS-DUO
The double feeding of the protective gas in the welding zone almost completely displaces the oxygen, creating an area close to technical vacuum. This process results in an extremely stable welding process and a weld that is twice as corrosion-resistant.
