Counter-Flow Evaporative Condenser
Lynxcool is a leading Chinese manufacturer of counter-flow evaporative condensers, operating its own production facilities. In a counter-flow design, air travels upward while cooling water flows downward — the two streams move in opposite directions, maximising the temperature differential across the heat-transfer surface and delivering outstanding condensing efficiency, particularly at high ambient temperatures.
The counter-flow evaporative condensers water and air as cooling media to exchange heat with high-temperature refrigerant gas inside the coil tubes, condensing the gas into liquid. Cooling water is distributed through spray nozzles onto the outer surface of the coils while axial fans draw ambient air upward through the unit. The opposing water and air streams create highly effective evaporative cooling: a portion of the water evaporates, absorbing large amounts of heat that is then exhausted to atmosphere. Drift eliminators capture entrained water droplets, returning them to the basin for recirculation. A float valve automatically replenishes water lost to evaporation.
What are the features of this machine?
Compared to conventional air-cooled or water-cooled condensers, the LynxB counter-flow evaporative condenser offers:
•Approximately 50% lower energy consumption vs. air-cooled or water-cooled equivalents
•Circulating water volume is only 1/8 that of a shell-and-tube + cooling tower system
•Counter-flow configuration maximises heat exchange efficiency at high ambient temperatures
•Wide capacity range from 450 kW to 3,250 kW — scalable to large industrial loads
•Compact footprint and low profile simplify installation and reduce civil engineering costs
•Pre-assembled before shipping to minimise on-site labour and commissioning time
•Long service life with minimal maintenance requirements and low lifecycle cost
Application Scope
The LynxB series is designed for large-scale industrial refrigeration and process cooling where high thermal efficiency and reliability are essential. Typical applications include:
•Large cold storage and food processing facilities
•Chemical, petrochemical and pharmaceutical plants
•Industrial air conditioning and process cooling systems
•Ammonia and Freon refrigeration systems
•District cooling and data centre thermal management
•Any application replacing conventional shell-and-tube condensers with cooling towers
Component Specifications
Each LynxB series Counter-Flow Evaporative Condenser includes the following carefully designed components:
|
Component |
Description |
|
Heat Transfer Coil |
Profiled high-frequency welded steel tubes with uniform wall thickness. Pressure-tested at 2.5 MPa, then hot-dip galvanized. The non-circular tube profile eliminates dry spots during spraying, significantly improving heat-exchange efficiency. |
|
Casing |
2 mm aluminium-zinc coated steel (Korean import). All cut edges sealed with zinc-rich paint to prevent corrosion. Optional stainless steel basin available. |
|
Spray System |
Large-flow, anti-clog basket-style nozzles mounted on corrosion-resistant PVC distribution pipes. Serviceable during operation. Nozzle spacing is precisely calculated to ensure continuous, uniform coil surface coverage. |
|
Drift Eliminators |
Multi-pass GRP (fibreglass) eliminators reduce drift loss to below 0.001%. Modular panels are individually removable for easy internal access. Also shields the unit from debris ingress and direct sunlight. |
|
PVC Fill Layer |
Honeycomb cross-flow PVC packing for uniform water distribution. Bio-corrosion resistant, non-brittle, and age-resistant for long service life. |
|
Circulation Pump |
Dedicated evaporative-condenser pump from a reputable brand: low wattage, high flow, low head, outdoor-rated. Optional electronic scale inhibitor available. |
|
Fan |
Axial fans with corrosion-resistant aluminium alloy hollow-injection blades installed in streamlined housings for maximum efficiency. Belt-driven centrifugal fans provide inherently low noise and can be serviced externally through side access panels. |
|
Sealing |
Imported high-temperature polyurethane sealant. Cures to a smooth, flexible finish — resistant to both high and low temperature extremes — for long-term leak prevention. |
Technical Specifications
All models are factory-tested and ship pre-assembled. Fan power values shown as start/run (kW) where applicable. Specifications are measured under standard rating conditions.

FAQ
Q1: What is a counter-flow evaporative condenser?
A: Air moves upward while water sprays downward, maximizing the temperature differential for higher efficiency. Co-current (down-flow) models have air and water moving in the same direction, giving lower efficiency. LynxB uses counter-flow for superior performance, especially in hot climates.
Q2: What refrigerants are compatible?
A: Ammonia (R-717) and common HFC/HCFCs (R-22, R-134a, R-404A, R-507). Coils are high-frequency welded carbon steel, hot-dip galvanized, suitable for ammonia. Specify refrigerant when ordering.
Q3: How much water and electricity does it consume?
A: Uses ~1/8 the water of a conventional shell-and-tube + cooling tower system and ~50% less electricity than equivalent air-cooled condensers. Water consumption is listed in each model’s technical table.
Q4: What is the standard operating temperature range?
A: Ambient dry-bulb -10 °C to +43 °C, wet-bulb up to 28 °C. For extreme conditions, contact Lynxcool for assessment and winterisation.
Q5: What anti-corrosion measures are incorporated into the unit?
● Coils: pressure-tested and hot-dip galvanized
● Casing: 2 mm Al-Zn steel, cut edges sealed
● Water piping: PVC
● Drift eliminators: GRP
● Optional SS basin (304/316L) for aggressive water
● Polyurethane sealant at all joints
Q6: How is the unit maintained, and how often is servicing required?
Minimal routine maintenance. Side panels allow inspection of belts, pump, and water system without shutdown. Annual tasks: belt tension, basin/fill cleaning, nozzle & eliminator check, electronic scale inhibitor inspection.
Q7: What water treatment is required?
Maintain pH 7–8.5, biocide dosing, and blowdown. Optional electronic scale inhibitor available. Hard water may require upstream softening.
Q8: How is the unit shipped and installed on site?
Units fully assembled and tested. On-site: position on pad, connect refrigerant, water, and electricity. Large models may require crane — check with Lynxcool.
Q9: Can the capacity be customised or multiple units be operated in parallel?
Yes. Standard: 450–3,250 kW per unit. Multiple units can run on a common header for higher capacity. Custom sizing available — provide heat load, wet-bulb, and condensing temperature.
Q10: What warranty and after-sales support does Lynxcool provide?
Standard 18-month warranty from commissioning or 24 months from shipment (whichever first), covering manufacturing defects. Wear parts excluded. Lynxcool provides service partners, spare parts, and optional extended support.
