Hengyou builds shell-and-tube heat exchange equipment for air-conditioning and refrigeration from 3 to 2,000 RT, in one to six refrigerant circuits, at two manufacturing sites in Guangdong. Every product on this site opens in three complete layouts.恒优在广东双基地制造空调及制冷用壳管式换热设备，制冷量覆盖 3 至 2000 RT，具备一至六个制冷回路。本站每个产品都提供三套完整版式。
Capacity is only the first question. What follows is how the shell is made, how the tubes are fixed, how the unit is cleaned and how the order is delivered.制冷量只是第一个问题。接下来是筒体如何制造、换热管如何固定、机组如何清洗，以及订单如何交付。
Published series span 86.5 kW to 3,400.2 kW of nominal cooling capacity, in single- and multi-circuit arrangements, matched to Hanbell RC2, scroll and third-party screw compressors.已公布系列的名义制冷量覆盖 86.5 kW 至 3400.2 kW，提供单回路与多回路形式，可配套汉钟 RC2、涡旋及第三方螺杆压缩机。
Both bases run CNC machining centres, CNC tube expanders, automatic welding machines and a 20 kW laser cutter; the tube bundles use high-efficiency internal and external screwed copper tube.双基地配备数控加工中心、数控胀管机、自动焊接机与 20000 W 激光切割机；管束采用高效内外螺纹铜管。
Tube-side covers unbolt for mechanical cleaning, and the catalogue lists vent and drain connections per model so the water side can be emptied and purged in place.管程端盖可拆卸以便机械清洗；画册按型号标注排气与排污接口，便于现场排空与冲洗水路。
Pressure-vessel manufacture and sales are covered by ISO 9001 and ISO 14001 certificates valid to 13 March 2028, and products are pressure tested before despatch.压力容器制造与销售已纳入 ISO 9001 与 ISO 14001 认证范围，有效期至 2028 年 3 月 13 日；产品出厂前经压力试验。
Screw-matched units, flooded and falling-film evaporators, chiller condensers and corrosion-resistant evaporators — the six families most often specified.螺杆配套机组、满液式与降膜式蒸发器、冷水机组冷凝器与耐腐蚀蒸发器 —— 最常被选用的六个系列。

The catalogue is not a single consistent dataset. Working conditions differ per series, refrigerant is not stated, and two model codes are inconsistent in the source. Everything that could not be resolved is listed openly rather than smoothed over.画册并非一份统一口径的数据集：各系列工况不同、未标注制冷剂，且有两处型号代码自相矛盾。凡未能确认的事项，本站一律公开列出而非含糊处理。
