Location: Oran, Algeria (Coastal/High-Salinity Environment) Solution Provider: Beijing Holtop Air Conditioning Co., Ltd. (Holtop) Contract Date: June 2024 Scope: Supply, Delivery, and Technical Support of 12 Customized Rooftop Units (RTUs)      Holtop is proud to have been selected as the HVAC partner for a major seawater desalination plant in Oran, Algeria. This critical infrastructure project requires robust and reliable climate control solutions to protect sensitive electrical and control equipment from a highly corrosive coastal environment. In June 2024, Holtop supplied 12 customized rooftop units (RTUs)designed specifically to meet the extreme challenges of this application, ensuring uninterrupted operation and longevity of the plant's internal systems.   Desalination plants present perhaps the most severe operating conditions for HVAC equipment:   • Extreme Corrosion: Salt-laden air rapidly accelerates corrosion, causing standard HVAC units to fail prematurely and jeopardizing critical equipment cooling.   • Reliability is Non-Negotiable: Plant operations are 24/7. Any HVAC failure can lead to shutdowns of sensitive control systems, resulting in massive financial losses and disruption of water supply.   • Harsh Climate: High ambient temperatures and intense sunlight place additional stress on cooling systems, demanding superior performance and heat rejection capabilities.   • Remote Location: Ease of maintenance and local technical support capabilities are crucial to minimize downtime.   The Holtop Solution: Engineered for Resilience      Understanding these critical needs, Holtop did not supply standard off-the-shelf products. Instead, we delivered a bespoke solution with the following specialized features:   Advanced Anti-Corrosion Protection: Marine-Grade Coating: Full-unit epoxy resin coating applied to all external and internal metal surfaces (casing,框架, drain pan, coils). Stainless Steel Components: Critical components such as screws, hinges, and drain pans were upgraded to 304 or 316 stainless steel to resist salt spray corrosion. Corrosion-Resistant Condenser Coils: Coils featured enhanced fin spacing and a special hydrophilic blue anti-corrosion coating to improve durability and maintain efficiency. 2. Robust Design for Maximum Uptime: Heavy-Duty Construction: Reinforced cabinets and structural frames to withstand high winds common in coastal areas. High-Efficiency Components: Branded compressors and ECM motors were selected for reliability, energy savings, and precise control in variable conditions. Integrated Control System: Smart controls with fault alarms and remote monitoring capabilities, allowing plant engineers to anticipate issues before they cause downtime.   Project Scope & Delivery   • Product: 12 Units of Holtop Customized Rooftop Units (RTUs)      The successful partnership with the Oran Desalination Plant underscores Holtop's capability to serve the world's most demanding industrial sectors. We move beyond standard commercial applications to deliver heavy-duty, customized climate solutions that ensure the reliability of critical infrastructure like water desalination plants.

The trial operation of the new location of Tianjin Ninghe District Chinese Medicine Hospital, which has attracted much attention recently, has commenced. The hospital’s fresh air conditioning system adopts Holtop’s digital energy recovery units, ensuring a high-quality, safe air environment and energy-efficient operation. This significantly enhances the hospital’s medical service capabilities and greatly improves patient satisfaction.   The Tianjin Ninghe District Chinese Medicine Hospital is a second-grade Class A hospital with traditional Chinese medicine as its distinctive feature. The relocation and construction project of the hospital is a key livelihood project determined by the District Committee and Government based on the overall development plan of the Qiaobei New Area. It is also a significant endeavor aimed at benefiting future generations, holding crucial significance in deepening medical and health reforms in Ninghe District, improving the medical environment for residents in the surrounding Qiaobei New Area, and effectively addressing the bottlenecks and constraints in the development of Chinese medicine hospitals.   Holtop has tailored optimized solutions for various areas within the hospital, including departments, wards, and lobbies. They have provided 75 sets of digital energy recovery fresh air units in multiple specifications and models. This expansion of the hospital campus aligns more closely with the modern hospital’s requirements for epidemic prevention, intelligence, and energy efficiency. It also supports the implementation of the “Healthy China” strategy by facilitating access to medical care for the public right in their local community. Holtop’s digital intelligent fresh air system utilizes supply air units to deliver fresh outdoor air into indoor spaces through a piping system. Meanwhile, exhaust air units treat and expel indoor air outdoors. By integrating monitoring data of indoor air quality with preset control logic, the system organizes airflow within the hospital building, ensuring orderly circulation and maintaining air quality in functional rooms.     Hospital buildings consume a significant amount of energy for ventilation and air conditioning, with ventilation and air conditioning accounting for over 50% of the total building energy consumption. To effectively utilize the energy in exhaust air and reduce system loads, Holtop’s digital energy recovery units adopt a liquid circulation-based heat recovery method. The supply and exhaust air units are relatively independent, completely eliminating cross-contamination between supply and exhaust air while efficiently utilizing exhaust air energy. This achieves energy savings and significantly reduces operating costs.       Holtop’s digital intelligent air conditioning system features a sophisticated control system network. The central control system employs intelligent analysis of monitoring data to dynamically adjust air parameters and indoor pressure gradients in real-time according to varying requirements, ensuring swift responsiveness. The control system automatically generates operation trend reports, energy consumption reports, maintenance reports, and fault point alerts, providing comprehensive insights into the system’s operation status, equipment power consumption, component wear, and more.         Holtop’s digital fresh air conditioning system can be systematically customized to suit different hospital buildings, meeting the requirements for air quality, air safety, low energy consumption, and intelligence during the transition to epidemic prevention. It has been widely used in the construction of many hospitals in China and has achieved excellent results in practice.
