Most engineers and facility managers know this frustration: you find a chiller with the right capacity, but the footprint is wrong. Or the voltage doesn't match your plant. Or you need -30°C brine temperature and the standard model bottoms out at -5°C. You call the supplier, and they say "sorry, standard model only."
That's the gap we fill. Not every cooling job fits a catalog spec sheet — and honestly, most industrial processes don't. Here's what actually matters when you need a chiller built around your requirements, not someone else's spec table.
**The Three Compressor Types — Pick the Right One**
Screw compressors handle the heavy lifting. 100 kW to 2,000+ kW range, continuous duty, 24/7 operation without breaking a sweat. If you're cooling a chemical reactor, a plastics injection line running three shifts, or a data center that can't afford a single minute of downtime — this is your workhorse. Maintenance interval: 8,000–12,000 hours. COP sweet spot: 4.5–5.5 under full load. We build screw chillers with Bitzer and Hanbell compressors, paired with Siemens PLC controls and Carel electronic expansion valves — components our engineers have been working with for over a decade.
Scroll compressors are the mid-range champion. 5 kW to 200 kW, modular design — stack multiple scrolls on one frame for redundancy. If one fails, the rest keep running. Food processing plants love this. Cold storage facilities too. The noise level is about 10 dB lower than screw, which matters when your chiller sits near the packaging line and operators are working 10 meters away. We use Copeland scrolls as standard, with full-load COP consistently above 3.2.
Piston compressors still have their place, especially in smaller installations (2 kW to 80 kW) and high-pressure applications. They tolerate dirty power better than scrolls. If you're in a region with unstable grid supply, or you need a chiller that can sit idle for months and fire up on demand — backup cooling, seasonal processes — piston is worth considering. Lower upfront cost per kW than screw or scroll.
**Non-Standard Means Non-Standard — Here's What We Actually Do**
Forget the marketing fluff. Real customization means real engineering changes, not just a different paint color. Here's what we deliver:
Low-temperature and ultra-low-temperature operation. Standard chillers bottom out around -5°C to 0°C. We routinely build units that deliver -30°C to -15°C brine temperature — essential for chemical batch reactors, pharmaceutical freeze-drying, and ice rink glycol systems. Different oil management, different expansion device sizing, different evaporator design. We've been doing this for 15 years, starting with ice sports refrigeration where -13°C glycol is the everyday baseline.
Explosion-proof configurations for chemical, pharmaceutical, and petrochemical applications. ATEX-compliant motor options, sealed electrical enclosures, spark-free fan designs. Documentation package includes material certificates, weld inspection reports, and full FAT (Factory Acceptance Test) protocols.
Voltage and frequency matching. 380V/50Hz for most of Asia and Africa. 460V/60Hz for North America. 400V/50Hz for Europe. We wind the motors accordingly — not just slap a transformer on the supply line.
Ambient temperature derating. A chiller rated at 35°C ambient loses about 8–12% capacity at 45°C. We oversize the condenser and adjust expansion valve sizing for Middle East and Southeast Asia installations. Our Qatar projects run chillers at 48°C ambient without capacity shortfall.
Corrosion protection. Coastal installations, chemical plants, wastewater treatment — standard copper-aluminum coils die in 2–3 years. We offer epoxy-coated fins, copper-copper coils, and full stainless steel cabinet options with IP65 controls enclosures.
Control integration. Modbus RTU, BACnet, or hardwired dry contacts. Your BMS talks to our chiller, not the other way around.
Noise constraints. Residential areas, hospital campuses, hotel basements all have noise limits. We spec compressor sound jackets, variable-speed condenser fans, and acoustic enclosures that drop the sound level from 75 dB(A) to below 60 dB(A) at 10 meters.
**Product Range — What We Build**
Standard and custom configurations across the full spectrum:
- Screw-type water-cooled and air-cooled chillers
- Scroll-type water-cooled and air-cooled chillers
- Water-to-water and ground-source heat pumps
- Air-source heat pumps (heating and cooling)
- Variable-frequency drive (VFD) chillers for part-load efficiency
- Explosion-proof chillers (ATEX-compliant)
- Ultra-low-temperature chillers (down to -30°C brine)
- Packaged monobloc screw chillers (single-frame, plug-and-play)
- Flooded evaporator chillers (higher efficiency, larger capacity)
- Falling-film evaporator chillers (reduced refrigerant charge)
- Evaporative-condenser chillers (extreme ambient performance)
- Air-cooled heat pump chillers (dual-mode heating + cooling)
Every unit is designed around the actual job site conditions and process requirements — not the other way around.
**Where These Chillers Actually Go**
Ice rinks are our home turf — glycol chillers running at -13°C to -10°C supply temperature, keeping ice surfaces at -4°C year-round. We've built them for mall ice rinks in Guangzhou, a sports complex in Wuxi, and a research-grade snow lab in Shandong.
But the same screw compressor platform that cools a 1,800㎡ ice rink also serves a plastics extrusion line in Fujian, a chemical batch reactor in Jiangsu, and a cold storage warehouse in Malaysia. The refrigerant circuit is the same physics. The control logic is what changes.
Chemical and petrochemical: reactor jacket cooling, condenser duty, solvent recovery. Typically screw-based, 100–800 kW, often with explosion-proof requirements and stainless steel heat exchangers. We supply full material traceability documentation.
Plastics and rubber: injection molding, extrusion lines, blow molding. Hydraulic oil cooling plus mold temperature control. Usually scroll-based, 30–200 kW, with dual-circuit design — one circuit for oil, one for mold.
Food and beverage processing: glycol or brine chillers for dough cooling, fermentation temperature control, chocolate tempering. Typically scroll-based, 30–200 kW, with sanitary-compatible heat exchangers (shell-and-tube or PHE with food-grade gaskets).
Pharmaceutical: freeze-drying (lyophilization), reactor cooling, cleanroom HVAC. Screw or scroll, 50–500 kW. Tight temperature control — ±0.5°C stability. Full IQ/OQ/PQ documentation package available.
Metalworking and laser cutting: precise temperature control for CNC spindles and laser optics. Tight tolerance — ±0.5°C stability. Piston or scroll, 5–50 kW.
Data centers: high-efficiency screw chillers with free cooling economizer modes. When ambient drops below setpoint, the chiller bypasses the compressor and uses outdoor air for partial cooling. Saves 30–40% on annual energy costs in temperate climates.
Printing, environmental control, metallurgy, automotive, electronics — the list keeps going. If your process generates heat and needs precise temperature control, we've probably built a chiller for something similar.
**Our Engineering Backbone**
We don't just assemble parts. Beijing Yangsheng has built strategic partnerships with the names that matter in industrial refrigeration: Bitzer (Germany) and Hanbell (Taiwan) for screw compressors, Copeland (Emerson, USA) for scroll compressors, Siemens for PLC control systems, and Carel (Italy) for electronic expansion and supervisory controls. These aren't transactional supplier relationships — our engineers have been working with these platforms for 15+ years.
Our management philosophy is built on T-E-Q-S: Technology, Energy efficiency, Quality, and Service. Every chiller that leaves our facility reflects that. From the CAD modeling of refrigerant pipe runs to the factory acceptance test protocol, we treat each unit as if it's going into our own facility.
**Real Capacity Ranges We Supply**
- Small process chillers: 2 kW – 50 kW (piston/scroll, air-cooled or water-cooled)
- Medium industrial chillers: 50 kW – 300 kW (scroll/screw, modular or packaged)
- Large industrial chillers: 300 kW – 2,000 kW (screw, water-cooled preferred)
- Multi-compressor configurations available across all ranges for N+1 redundancy
**What to Expect on Timeline and Shipping**
- Standard chillers with minor customization (voltage swap, control protocol change): 4–6 weeks from PO to ex-works
- Fully custom chillers (non-standard capacity, special materials, custom footprint): 8–12 weeks
- Shipping from our facility near Beijing: 10–20 days sea freight to Middle East, 20–35 days to Europe, 15–25 days to Southeast Asia. Air freight available for urgent orders (3–7 days)
We ship EXW or FOB. If you need us to handle freight forwarding and destination clearance, we can coordinate through our logistics partners.
**The Bottom Line**
If a standard chiller from a catalog fits your job, buy it. Don't pay for custom engineering you don't need.
But if your cooling requirement has an asterisk — unusual voltage, low-temperature brine, corrosive environment, tight footprint, explosion-proof rating, or a BMS that needs to play nice — that's when you talk to a supplier who doesn't just sell boxes. We design chillers around your process, not the other way around.
Got a spec sheet or a rough cooling load? Send it over. We'll give you a configuration proposal and a ballpark price within 3 business days. No obligation, no sales pressure — just an honest assessment of what works.
