OBAIR Supports Green Manufacturing with Efficient HVAC Solution for Hebei Shuangda

As industrial manufacturing accelerates toward smarter and more sustainable development, reliable and energy-efficient climate control is becoming increasingly important for modern production facilities.

To support the development of Hebei Shuangda Petroleum Equipment Manufacturing Co., Ltd.’s intelligent oilfield equipment facility, OBAIR provided an integrated HVAC solution combining flooded ground-source heat pump units with cabinet-type fan coil units. The system is designed to deliver stable heating and cooling, high operational reliability, and improved energy efficiency for long-term industrial operation.

Climate Control for Intelligent Petroleum Equipment Manufacturing

Founded in 2015, Hebei Shuangda Petroleum Equipment Manufacturing Co., Ltd. specializes in centrifugal pumps for petroleum, chemical, and natural gas applications in accordance with API 610 standards.

The new manufacturing facility covers approximately 33,333 m² and includes machining, production, assembly, and quality inspection areas. Once fully operational, the project is expected to achieve an annual production capacity of up to 5,000 sets of industrial pumps, pump skid systems, and intelligent oilfield equipment.

For precision manufacturing environments, stable indoor temperature is essential for machining accuracy and equipment performance. At the same time, continuous production places high demands on HVAC reliability, energy efficiency, and ease of maintenance.

To meet these requirements, OBAIR developed a complete solution covering both the central heating and cooling source and terminal air distribution system.

Integrated Ground-Source Heat Pump Solution

The project adopts a combination of:

Flooded Ground-Source Heat Pump Units + Cabinet-Type Fan Coil Units

The ground-source heat pump system serves as the central cooling and heating source, while cabinet-type fan coil units provide conditioned air to different production areas.

By utilizing the relatively stable underground thermal environment, the system provides cooling in summer and heating in winter, helping reduce energy consumption while maintaining consistent indoor conditions.

The flooded ground-source heat pump units are equipped with semi-hermetic twin-screw compressors, continuous slide-valve capacity control, high-efficiency flooded evaporators, and reliable oil separation and return systems.

These features enable efficient operation under both full-load and part-load conditions while supporting the long operating hours required in industrial applications.

An integrated PLC control system with a touchscreen interface provides real-time monitoring, intelligent control, and comprehensive system protection, simplifying daily operation and maintenance.

Flexible Air Distribution for Different Production Areas

OBAIR cabinet-type fan coil units provide flexible terminal solutions for different spaces within the facility.

Available configurations include ceiling-mounted, vertical, long-distance jet air supply, and customized designs, allowing the system to adapt to various production layouts and airflow requirements.

The product range covers:

• Airflow: 1,600–58,000 m³/h

• Cooling capacity: 11.2–795 kW

• External static pressure: 120–600 Pa

Featuring aluminum-alloy frames, color-coated steel panels, centrifugal fans, high-efficiency heat exchangers, and double-layer nylon filters, the units are designed for stable operation and convenient maintenance.

Enabling Efficient and Sustainable Production

Through the integration of the central heating and cooling system with flexible terminal air-conditioning equipment, OBAIR has established a complete environmental control solution for the project’s machining, assembly, inspection, and auxiliary areas.

The solution helps maintain stable production conditions while improving energy efficiency and supporting the customer’s transition toward smarter and more sustainable manufacturing.

With extensive experience in industrial HVAC applications, OBAIR continues to deliver efficient, reliable, and application-focused climate control solutions for customers worldwide.
