The ZL-10T's 35.2 kW cooling capacity provides summer climate control for greenhouses in the 100-500 m² range:
Cooling load calculation: Greenhouse summer cooling load = 0.3-0.5 kW/m² (mid-latitude summer, single-glazed glass or polycarbonate, shade cloth deployed).
Coverage by greenhouse size:
100 m² greenhouse: 30-50 kW cooling load. ZL-10T (35.2 kW) at 70-100% utilization. Match for crop cooling in moderate climates.
200 m² greenhouse: 60-100 kW cooling load. ZL-10T undersized. Use ZL-30T (110 kW) or ZL-40T (140 kW).
300 m² greenhouse: 90-150 kW cooling load. ZL-50T (160 kW) recommended.
500 m² greenhouse: 150-250 kW cooling load. ZL-80T (270 kW) or larger.
For a typical 100-150 m² greenhouse growing tomatoes, cucumbers, or peppers, the ZL-10T paired with a pad-and-fan ventilation system delivers optimal summer climate control. The ZL-10T cools the recirculated water for the pad system, providing 8-12°C temperature reduction across the pad for incoming outside air.
In craft brewery and small-scale commercial brewery applications, the ZL-10T provides primary cooling for wort cooling (post-boil to fermentation temperature) and fermenter temperature control:
Wort cooling load: Boiled wort exits the brew kettle at 98-100°C and must be cooled to 18-22°C for yeast pitching. Typical 300 L batch: 300 L × 4.186 kJ/kg°C × 78°C ΔT = 98 MJ = 27.2 kWh per batch. At 2-hour cooling target: 13.6 kW average cooling load.
ZL-10T matching: ZL-10T provides 35.2 kW cooling capacity, comfortably above the 13.6 kW average for 300 L batches. Cooling time: 2-2.5 hours per batch.
Plate heat exchanger pairing: Direct contact between cooling tower water and wort is not permitted (sanitation). Use a plate heat exchanger: wort on one side, cooling tower water on the other. Heat transfer rate: 15-25 kW per heat exchanger in this flow range.
Fermenter temperature control: After wort cooling, fermenters generate 0.5-1 kW of metabolic heat during the 5-7 day fermentation. The ZL-10T's residual capacity (after wort cooling) maintains fermenter temperature via a secondary cooling loop with a smaller plate heat exchanger.
For dairy processing operations, the ZL-10T provides cooling water for HTST (High-Temperature Short-Time) pasteurization systems and batch pasteurizers:
HTST pasteurization: Milk heated to 72°C for 15 seconds, then rapidly cooled to 4°C. Cooling load for a 1,000 L/hour HTST line: 1,000 L/h × 4.186 kJ/kg°C × 68°C ΔT = 285 MJ/h = 79 kW cooling load.
ZL-10T capacity: 35.2 kW cooling capacity is undersized for HTST (requires ZL-60T or larger). Suitable for batch pasteurizers (200-500 L batches).
Batch pasteurization: 300 L milk heated to 63°C for 30 minutes, then cooled to 4°C. Cooling load: 300 L × 4.186 × 59 = 74 MJ = 20.6 kWh per batch. At 1-hour cooling target: 20.6 kW cooling load.
Plate heat exchanger + ZL-10T: Plate heat exchanger transfers heat from milk to cooling tower water. ZL-10T cools the water, which recirculates back to the heat exchanger. Cooling time: 60-90 minutes per 300 L batch.
For dairy operations, specify the SS316L sanitary option with sanitary tri-clamp connections for clean-in-place compatibility.
For slaughterhouse operations, the ZL-10T serves multiple cooling applications:
Carcass cooling: Post-slaughter, beef and pork carcasses are cooled from 38°C (body temperature) to 4°C (refrigeration temperature) over 24 hours. The cooling load depends on carcass mass and ambient conditions. For a small-to-medium slaughterhouse processing 50-100 animals per day, total carcass cooling load: 50-100 kW.
Process water cooling: Slaughter operations use warm water for cleaning (40-45°C) and chilled water for carcass spray cooling (1-2°C). The chilled water loop requires cooling tower + chiller pairing. ZL-10T provides the primary cooling; chiller handles the low-temperature target.
ZL-10T for slaughterhouse: The ZL-10T is suitable for small operations (10-30 animals/day) where process water cooling is the primary application. For larger operations, step up to ZL-30T or larger.
Sanitary design requirements: Specify SS316L construction, sanitary tri-clamp fittings, and sloped basin drainage for CIP compatibility. Daily CIP cycles are essential to prevent bacterial growth in the cooling water circuit.
For mushroom cultivation facilities (shiitake, oyster, button mushrooms), the ZL-10T serves substrate cooling during phase II composting and climate control during fruiting:
Substrate cooling (post-pasteurization): After phase II composting at 55-60°C, substrate must cool to 25°C for spawning. Cooling load for 1 tonne of substrate: 1,000 kg × 4.186 kJ/kg°C × 30°C ΔT = 126 MJ = 35 kWh per tonne. For a small mushroom farm processing 1-2 tonnes/day, ZL-10T capacity (35.2 kW) provides 1-2 hour cooling cycles.
Fruiting room climate control: Mushroom fruiting requires 14-18°C air temperature, 85-95% humidity, and CO2 <1,000 ppm. The ZL-10T's 32°C leaving water is suitable for cooling humidification water (typically chilled to 15°C with a chiller).
ZL-10T sizing for mushroom farm: For a 100-200 m² mushroom cultivation facility, ZL-10T supports substrate cooling and provides primary cooling for fruiting room climate control.
Sanitation requirements: Specify SS316L + sanitary piping for food-contact applications. Daily sanitization between substrate batches is essential to prevent Trichoderma and other contaminant molds.
For aquaculture (fish farming) and hydroponic crop production, water temperature stability is critical for animal/plant health and growth rates. The ZL-10T provides primary cooling for recirculating aquaculture systems (RAS) and hydroponic nutrient solutions:
Aquaculture (warm-water species): Tilapia, catfish, and shrimp thrive at 26-30°C. In summer, recirculating system water can exceed 32°C, reducing growth rates and increasing disease risk. ZL-10T's 32°C cooling water (recirculated through plate heat exchanger) maintains aquaculture tank temperature at 28°C ± 1°C.
Hydroponic nutrient solution: Lettuce, herbs, and strawberries grow best with nutrient solution at 18-22°C. In summer greenhouse hydroponic systems, nutrient solution can reach 28-32°C, reducing dissolved oxygen and causing root rot. ZL-10T cools the nutrient solution to 22°C ± 2°C through a plate heat exchanger.
Aquaponics integration: Combined fish-and-plant systems benefit from ZL-10T's stable cooling: fish tank water cools through heat exchanger, then flows to plant grow beds as both irrigation and nutrient source.
Sizing rule of thumb: For aquaculture/hydroponic applications, ZL-10T supports 1,000-2,000 L of recirculating water with 1°C temperature differential. Larger systems require ZL-30T or ZL-50T.
Sanitation: UV sterilization or ozone treatment of recirculating water prevents pathogen buildup in aquaculture systems. ZL-10T's stainless steel upgrade option supports chlorination-based cleaning protocols.
ZL-10T (35.2 kW cooling capacity) supports 100 m² greenhouse at 70-100% utilization. For larger greenhouses (200 m², 300 m², 500 m²), step up to ZL-30T, ZL-50T, or ZL-80T respectively.
Yes. For 300 L batches (cooling from 98°C to 22°C), the ZL-10T's 35.2 kW capacity provides 2-2.5 hour cooling. Pair with a plate heat exchanger for sanitary wort-to-cooling-water separation.
For batch pasteurizers (200-500 L batches), the ZL-10T is adequate. For HTST systems (1,000+ L/hour), the ZL-10T is undersized — use ZL-60T or larger. Specify SS316L + sanitary tri-clamp connections for dairy.
For small slaughterhouses (10-30 animals/day), the ZL-10T serves process water cooling. For larger operations (50-100 animals/day), step up to ZL-30T or larger. Specify SS316L + CIP-compatible sanitary piping.
For mushroom cultivation, ZL-10T supports 1-2 tonnes/day substrate cooling and primary fruiting room cooling. For aquaculture (tilapia, catfish, shrimp), ZL-10T maintains 1,000-2,000 L recirculating water at ±1°C temperature stability.
