From a small workshop in Foshan to a global exporter serving 30+ countries — our journey of quality and innovation.
AquaChill Tech (aquachilltech.com) is the official global export brand and website of Foshan Delin Cooling & Heating Equipment Industrial Co., Ltd. (Delin HVAC) — the Chinese manufacturer behind our seafood constant temperature machines, industrial water chillers, titanium evaporators, and stainless steel heat exchangers.
Founded in 2002, Foshan Delin Cooling & Heating Equipment Industrial Co., Ltd. started with a simple mission: to provide reliable, high-quality refrigeration solutions at factory-direct prices.
Over the past two decades, we have grown from a small team into a modern manufacturing facility spanning 8,000 square meters, equipped with advanced CNC machining centers, automated welding production lines, and comprehensive testing laboratories.
Today, Delin employs over 150 skilled workers and engineers, producing more than 50,000 units annually. Our products are exported to Southeast Asia, the Middle East, Africa, Europe, and South America, serving industries from seafood processing to industrial manufacturing.
Modern facilities and rigorous quality management ensure every product meets international standards.
CNC machining centers, automatic welding robots, and precision testing instruments ensure manufacturing accuracy.
100% hydrostatic pressure testing, performance verification, and multi-point inspection before shipping.
CE, ISO 9001, and SGS certified. Our quality management system meets international standards.
Since 2002, Delin has specialized exclusively in refrigeration and heat exchange manufacturing. Two decades of focused work — from titanium coil welding to chiller assembly — means our engineers have seen the failure modes that short-lived suppliers never learn about, and every design in our catalog is built on lessons from real seafood tanks, industrial chillers, and heat exchangers operating across 30+ countries.
We are the manufacturer, not a trading company. Our 8,000 m² factory in Foshan with over 150 employees produces more than 50,000 units a year, so you buy at factory cost with no middleman markup. Direct pricing also means transparent lead times — 15-25 days standard, 25-40 days for custom OEM builds — and a 24-month warranty backed by the people who built the machine.
Every Delin project starts from your specification, not a catalog page. We customize capacity, voltage (including 60 Hz), refrigerant, condenser type, titanium coil geometry, connection sizes, and OEM branding. Need to validate before mass production? We build prototypes for fit and performance testing first, then scale to full production with your packaging and documentation.
Quality at Delin is verifiable, not promised. Every titanium coil and heat exchanger is 100% hydrostatically pressure-tested, every chiller run-tested, and every weld checked by qualified TIG welders working to ASME IX. The factory holds CE and ISO 9001 certification, with SGS third-party inspection available on request, and incoming material is inspected before production and finished units again before packing.
Delin ships to more than 30 countries across Southeast Asia, the Middle East, Africa, Europe, and South America — from Saudi Arabian pool projects and South African hatcheries to seafood processing lines across Latin America. We build for your destination: 50 Hz or 60 Hz supply, single or three phase, English, Spanish, Portuguese, and Arabic documentation, and export packaging sized for ocean freight.
Our sales engineers answer within 24 hours, and the same team helps after delivery with installation guidance, water-flow configuration, and set-point advice. Because we build the equipment, you talk to engineers who know the machine, not a call center. Every order ships with a 24-month warranty, and replacement parts and spares are available direct from the factory for the life of the equipment.
