The company has partnered with Shenshi Heat Exchanger Co. to provide distribution and engineering support of coaxial-style heat exchangers for North American markets. The heat exchangers utilize a spirally enhanced inner tube surface to achieve greater heat transfer and optimized fluid flow. The inner tube enhancement provides up to 350 percent greater efficiency than straight tubing and allows for higher internal burst limits and compression strength, according to the company. The units are shaped into either circular or rectangular coils, allowing for a compact design. Available single circuit configurations include circular, rectangle, double-wall vented, and custom shapes from 1/2- to 8-ton capacities. Multiple circuit products for higher capacities and lower pressure drops are also available. Custom shapes and configurations are also available.
