The project, executed under the general contract of Chengda Engineering Corporation and operated by Nakhodka Mineral Fertilizer Plant, represents a significant reference for Chinese HVAC suppliers in large‑scale overseas energy‑chemical ventures. The plant encompasses a wide array of functional areas – including processing units, laboratories, warehousing, GIS substations, and security posts – each imposing distinct thermal and humidity control demands. Compounding the complexity are the region’s severe winter climate, the presence of corrosive gases, and explosion‑hazard classifications across methanol handling zones. Moreover, the local Russian regulatory framework and the use of 95/70°C high‑temperature hot water as the primary heat source required engineering adaptations beyond domestic Chinese practice. Holtop supplied more than 600 air handling units, encompassing constant‑temperature‑and‑humidity models, modular air handlers, direct‑expansion units, and an integrated control architecture. Key technical responses included: Distributed zoning control, enabling a single unit to regulate multiple independent spaces via terminal reheating and humidification stages, thereby eliminating the inaccuracies associated with uniform air delivery. Hot‑water mixing regulation, which reduces the incoming water temperature to a stable 80/70°C at the coil inlet, preserving heat exchange efficiency and safeguarding equipment from thermal stress. Full explosion‑proof construction for all electrical components, combined with corrosion‑resistant casings meeting European standards, ensuring safe operation in both hazardous and chemically aggressive environments. Centralised smart management built on a PLC‑based DCS architecture, with over 500 I/O points and a trilingual human‑machine interface (Chinese, English, Russian) to facilitate on‑site monitoring by multinational crews. The entire system passed joint acceptance by the contractor and owner on the first attempt, following on‑site commissioning by Holtop’s dedicated team. Complete technical documentation was delivered in three languages to align with Russian statutory requirements. The Nakhodka project demonstrates Holtop’s capacity to deliver fully customised, standards‑compliant HVAC solutions for complex industrial sites abroad. The company continues to advance its intelligent and energy‑efficient product portfolio, aiming to support the environmental control needs of energy and chemical infrastructure worldwide. About Holtop Holtop develops and manufactures energy‑recovery ventilation, air handling, and precision climate control systems for industrial, commercial, and institutional applications, with a focus on custom engineering and lifecycle service support.

The program, administered by six municipal agencies including the Beijing Science & Technology Commission and the Zhongguancun Administrative Committee, features a rigorous review process focused on green, low‑carbon technologies. Against China’s “dual‑carbon" goals, this year’s certification placed extra emphasis on high‑efficiency, energy‑saving products, giving the award strong industry authority. Outstanding performanceThe awarded ventilator delivers a total heat exchange efficiency of 76%, cooling and heating energy recovery coefficients of 14 and 11 respectively, and a net fresh air supply rate of 96.3%. By recovering both sensible and latent heat from exhaust air, it significantly cuts building energy consumption while physically isolating supply and exhaust streams to prevent cross‑contamination – combining efficiency with air safety. Technology at the coreHeat recovery is HOLTOP’s foundational strength, embedded across its full product range, including custom air‑handling units, direct‑expansion air conditioners (with over 50% energy savings), condensing exhaust heat recovery units, and total‑heat‑recovery air‑cooled heat pumps that achieve 100% waste‑heat reuse. These solutions are widely applied in residential, commercial, institutional, and industrial buildings. Future commitmentHOLTOP will continue to invest in R&D for energy‑efficient air treatment, driving green transformation in the HVAC industry while staying true to its mission: “Making Air Treatment Healthier, More Comfortable, and More Energy‑Efficient." About HOLTOPHOLTOP is a high‑tech enterprise focused on air heat recovery and energy‑saving ventilation/air‑conditioning solutions, serving customers worldwide with innovative, high‑performance products.

The campus will host 20,000 racks in total; Building 5 alone supports about 3,000 high-density racks for AI training, cloud, and big data. How do you cool 30 kW+ racks without wasting server space? HOLTOP’s units sit on the roof, eliminating the need for dedicated mechanical rooms inside the data hall. This frees every square metre for additional IT equipment, cuts civil construction costs, and enables rapid deployment – simply connect piping and power to start. What about hotspots and fluctuating loads? Advanced intelligent controls adjust cooling in real time, maintaining temperature within ±2°C and humidity within ±10% RH – critical for GPU clusters where thermal throttling can cripple performance. Why chemical filtration? Outdoor air contains sulfides, nitrides, and chlorides that corrode electronics. HOLTOP’s chemical filters remove these pollutants to meet ISA‑71.04‑2013 G1 (copper coupon
