Refrigeration Design
Thermodynamic Loop & Pressure Vessel Engineering
Specialized thermodynamic and mechanical engineering for commercial and industrial refrigeration systems. We design high-efficiency, eco-friendly systems using natural Low-GWP refrigerants (CO2 / R744 and R290 Isobutane) with optimized COP performance.
Engineering depth, delivered with precision.
At Dezitech Engineering, our refrigeration design capability is built on practical shop floor reality. We combine specialist engineering analysis with firsthand knowledge of CNC machining, gear cutting, and certified ISO assembly.
Avoid F-Gas phase-downs with engineered natural refrigerant architectures that reduce carbon footprint while boosting seasonal energy performance.
