Delta T Thermal Solutions is the exclusive global manufacturer of three specialized heat exchanger product lines that have become benchmarks in industrial thermal management: PLATECOIL, MAXCHANGER, and ECONOCOIL. With over eighty years of experience, the company has built its reputation on providing reliable, versatile, and efficient solutions for industries where precise temperature control is crucial to safety, quality, and efficiency. From chemical production to food processing and marine systems, Delta T equipment is designed to solve practical challenges such as space constraints, corrosion resistance, and energy recovery.
At the core of the company’s portfolio is the PLATECOIL series, a family of prime surface heat exchangers. These units feature die-formed passages that maximize surface contact for even heating or cooling. They are manufactured in two main configurations: single-embossed and double-embossed. Single-embossed designs, with passages formed on one plate, are ideal when mounted against a tank wall or other solid surface, providing efficient heat transfer while keeping the assembly compact.
Double-embossed plates, which have passages formed on both plates, are stronger and provide higher flow capacity, making them particularly effective in immersion heating or cooling. This flexibility allows PLATECOIL exchangers to adapt to many process conditions. They can be built into jacketed vessels for chemical reactors, suspended in food kettles for direct immersion heating, or clamped onto storage tanks for external temperature control. In confectionery production, PLATECOIL panels are integrated into fluidized beds to manage cooling during coating processes. In industrial exhaust systems, they are used for heat recovery, which improves overall plant efficiency. Their rugged prime surface construction means they operate reliably even in demanding conditions where other designs might foul or degrade.
The MAXCHANGER line addresses a different need: delivering the performance of a shell-and-tube exchanger in a smaller, lighter package. Its patented variable interspace geometry promotes turbulence, significantly boosting heat transfer efficiency compared to conventional designs. The compact footprint and reduced mass make MAXCHANGER particularly valuable in space-limited environments, such as offshore platforms or retrofit installations in crowded mechanical rooms. Engineers also appreciate the flexibility of nozzle configuration, which simplifies piping arrangements and installation.
MAXCHANGER exchangers are well-suited for handling corrosive fluids, extreme pressures, and high operating temperatures, making them ideal for chemical plants, oil and gas operations, and other heavy industrial processes where both durability and compactness are critical. The ability to orient nozzles in multiple directions provides a degree of freedom that standard shell-and-tube exchangers cannot match, allowing designers to integrate them more easily into existing systems without major piping modifications.
For lighter-duty service, the ECONOCOIL product line offers a practical balance of efficiency and economy. These plate-type exchangers are designed to deliver high thermal performance in applications that do not demand the heavy-duty construction of PLATECOIL or MAXCHANGER. ECONOCOIL units are widely used in plating and metal finishing shops, where tight temperature control ensures product quality, and in pulp and paper operations, where they regulate process water temperatures. Textile manufacturers employ them to maintain dye bath consistency, while wastewater treatment facilities use them for heating or cooling streams to optimize biological or chemical processes. The pharmaceutical and food industries also rely on ECONOCOIL for reliable, cost-effective heating and cooling in batch production environments. While lighter in construction, they still offer the efficient heat transfer that industrial operations require.
A key strength across all three product lines is Delta T Thermal Solutions’ ability to tailor designs and materials to meet specific application needs. Units can be fabricated from carbon steel for general service or from stainless alloys where corrosion resistance is essential. Material selection directly affects performance and longevity; the company’s engineering team works closely with customers to match construction to specific operating conditions. The result is equipment that not only transfers heat effectively but also withstands the rigors of long-term industrial service. This customization extends to physical form as well, whether shaping PLATECOIL panels to fit irregular vessel contours, configuring MAXCHANGER units with unconventional nozzle orientations, or specifying ECONOCOIL exchangers for specialized wastewater chemistries.
Across industries ranging from food and beverage to pharmaceuticals, petrochemicals, and renewable energy, Delta T Thermal Solutions has established itself as a trusted partner in heat transfer. Its products solve the daily challenges engineers face: fitting high-capacity exchangers into tight spaces, maintaining precise process temperatures, resisting corrosion, and improving energy efficiency. By combining proven designs with flexible engineering support, the company ensures that its equipment consistently delivers performance, reliability, and value.
