Kilterra heat exchangers are custom-engineered to customer operating conditions with stable batch delivery and technical support.
Six core advantages that keep your refrigeration system protected around the clock
A seamless steel-tube shell with no circumferential welds removes weld-leak risk at the source.
A unique internal baffle design distributes refrigerant evenly on the shell side, avoiding local poor transfer.
Passes 230,000 pressure-fatigue cycles, far beyond industry norms, for frequent start/stop duty.
The same unit works as condenser or evaporator by changing connection positions, lowering inventory.
Refrigerant side 4.2MPa / water side 1.5MPa for high-pressure refrigerant systems.
KLDS-25 to KLDS-130 cover 25-130kW for commercial and industrial duty.

When specifying a heat exchanger for chillers or commercial refrigeration, confirm the duty in kW, refrigerant type, and the temperature approach required between water and refrigerant, since a tighter approach increases tube count and cost. Verify the shell and tube materials suit the fluid: seamless steel for standard R134a and R404A duty, or stainless steel where ammonia or corrosive water is involved. Check the pressure rating against your condensing pressure, and confirm connection sizes match existing pipework to avoid adapters. Kilterra supplies these units to OEMs across Europe, the Middle East, and Southeast Asia, with batch testing and documentation for export compliance.
When specifying a heat exchanger for chillers or commercial refrigeration, confirm the required heat transfer capacity in kW, the refrigerant and secondary fluid temperatures, and whether the unit serves as a condenser or evaporator, since these determine tube count, shell diameter, and baffle spacing. Kilterra manufactures shell and tube units from 25kW to 130kW with seamless steel shells, tested to 230,000 fatigue cycles, and supports OEM buyers with custom connection sizes, materials, and batch-consistent delivery for export markets.
Selecting a heat exchanger for refrigeration duty starts with matching heat transfer area to your actual kW load, not just the nominal rating. Confirm tube-side and shell-side flow rates, allowable pressure drop, and whether the unit serves as condenser or evaporator, since baffle spacing and pass configuration differ between duties. For export projects, specify shell and tube materials compatible with local refrigerant and water quality, and request fatigue-cycle test data. Kilterra supplies 25β130kW shell and tube heat exchangers with documented 230k-cycle endurance, stable batch delivery, and technical support for OEM chillers and ice machines.
When specifying a heat exchanger for chillers or commercial refrigeration, confirm the heat transfer area against your actual condensing and evaporating temperatures rather than nominal tonnage, since oversizing raises refrigerant charge and undersizing causes high discharge pressure. Kilterra builds shell and tube units from 25kW to 130kW with seamless steel shells, internal baffles for uniform flow, and connections sized to your pipework, and supports OEM buyers with batch delivery, material certificates and export documentation for markets in Europe, the Middle East and Southeast Asia.
When specifying a heat exchanger for commercial refrigeration, confirm the duty in kW, the refrigerant type, and whether it serves as condenser or evaporator, since these determine tube count, baffle spacing, and shell diameter. Kilterra builds units from 25 to 130kW with seamless steel shells and internal baffles that promote uniform flow and reduce fouling. Units are pressure-tested and fatigue-verified to 230k cycles, and we export to chillers, cold storage, and process cooling projects worldwide with batch delivery and technical support.
When specifying a heat exchanger for chillers or condensing units, confirm the heat transfer area matches your kW duty at the actual approach temperature, not just the nominal rating. Tube pass configuration, baffle spacing and refrigerant-side pressure drop all affect performance: excessive drop reduces compressor efficiency, while too little turbulence lowers the overall U-value. For R134a, R404A, R410A and CO2 systems, material selection (carbon steel shell with copper or stainless tubes) should follow the refrigerant and water quality. Kilterra supplies 25-130kW units with seamless welded shells, tested to 230,000 fatigue cycles and exported to over 40 countries.
Selecting a heat exchanger for refrigeration duty starts with matching the heat transfer area to your kW load and refrigerant type, then confirming shell-side and tube-side pressure ratings against your system's high-side design pressure. For chillers and condensing units, counter-flow tube arrangements improve approach temperatures, while removable tube bundles simplify mechanical cleaning in hard-water regions. Kilterra supplies seamless shell units from 25 to 130kW with internal baffles for uniform flow, and supports OEM buyers with material certificates, connection customization and export documentation for markets across Europe, the Middle East and Southeast Asia.
Correct sizing of a heat exchanger depends on matching heat transfer area to the actual duty cycle, not just the nominal kW rating. For chillers and commercial refrigeration, confirm refrigerant type, operating pressures, fouling allowance and connection orientation before selecting a 25-130kW shell and tube unit. Seamless steel shells with internal baffles maintain uniform flow and resist vibration fatigue, while dual condenser/evaporator capability simplifies spare-parts planning. Kilterra supplies these exchangers to OEMs and contractors across Europe, the Middle East and Southeast Asia, with batch consistency and documentation suited to export orders.
