Applications
HVAC & Heat Pump
High-efficiency tube solutions for chillers, heat pumps and demanding heating and cooling systems.
Heat pumps, chillers and refrigeration systems all come down to the same thing: moving heat efficiently, in a compact envelope, with a refrigerant on one side and water or air on the other. The tube is where that happens.
NEOTISS supplies welded tubes for HVAC and heat pump heat exchangers to equipment manufacturers worldwide — from residential and commercial heat pumps to large industrial chillers and evaporative condensers.
Why enhanced tubes matter here
In HVAC and heat pump applications, heat exchanger performance drives the coefficient of performance of the whole machine. A tube that transfers more heat per unit of surface lets the manufacturer either raise efficiency at constant size, or hold efficiency in a smaller and cheaper unit.
Our integral low-fin and inner-grooved geometries are built for exactly that trade-off. NEOTISS™ HPT Finned Tubes deliver 2.5 to 3 times the external surface area of a smooth tube, and internal ridging raises the refrigerant-side coefficient where the process is ID-controlled.
Typical applications
- Heat pump evaporators and condensers — residential, commercial and industrial
- Water-cooled and air-cooled chillers
- Refrigeration condensers, including ammonia evaporative condensers
- Blast freezers and cold storage systems
- Shell-and-coil and compact immersion heat exchangers
Materials
- Stainless steel — austenitic, ferritic and duplex grades for aggressive water chemistry
- Titanium — seawater and swimming-pool applications, complete resistance to chlorides
- Copper alloys and Cu-Ni — Thermo-C and Thermo-B enhanced geometries for condensing and nucleate boiling duties
- Carbon steel — cost-driven industrial refrigeration duties
Working with equipment manufacturers
HVAC is a volume business with tight cost targets and demanding qualification cycles. Our applications engineers work with OEM design teams from the thermal specification stage, using HTRI simulation to compare geometries before any tube is produced — so the trade-off between performance, cost and manufacturability is settled early rather than discovered late.
