Our customized solutions maximize thermal efficiency and process savings. The MECS-ThermoZ™ Fully-Welded Plate Heat Exchanger recovers waste heat from hot gas streams, which may otherwise be stack-vented to the atmosphere. Recovered heat is then used within the plant to heat or preheat another gas stream for use in other processes. That allows plants to optimize energy and process efficiency, achieve significant savings and improve cost-effectiveness.
Backed by our decades of process experience, dedicated Elessent Clean technologies engineers can custom-design and furnish a MECS-ThermoZ™ gas-to-gas solution to meet your organization’s application needs, yielding optimum performance and energy efficiency.

所有 MECS® gas-to-gas heat exchangers — including MECS-ThermoZ™ — feature a compact, modular design and long service life. The units are shop-fabricated to ensure quality, and trucked as individual blocks or complete modules. With their compact size and weight, installation and field setup are much simpler than with conventional shell and tube heat exchangers. And because the MECS-ThermoZ™ Fully-Welded Plate Heat Exchanger has no moving parts, it requires virtually no maintenance.
The MECS-ThermoZ™ Fully-Welded Plate Heat Exchanger is available in both cross-flow and counter-flow configurations. Our modular approach enables us to offer one of the most flexible and efficient flow arrangements available, as well as the flexibility to expand to accommodate future increases in capacity. This modular approach also enables significant design and operational customization, including the freedom to select distinct materials of construction for each heat transfer zone. Each module can be fabricated from a variety of heavy-gauge carbon steel and stainless steel plates, including COR-TEN®, 304L, 316L, and 309S. Heavy-duty MECS-ThermoZ™ units, built with robust materials, can deliver reliable and efficient performance in the most demanding, corrosive, and high-temperature applications, up to 1500°F (816°C).
Thanks to our heavy-duty design, robust fabrication, and the proper selection of construction materials, MECS-ThermoZ™ is delivering highly reliable performance in demanding applications such as:
Our distinctive units feature a unique plate dimple design that achieves outstanding heat transfer efficiency. The MECS-ThermoZ™ Fully-Welded Plate Heat Exchanger consists of a series of stacked, parallel plates that provide a smooth, continuous gas flow path, for minimum air resistance and very low pressure drop. The heat transfer plates are completely seam-welded, to prevent cross-contamination. Spacing is achieved with a combination of raised and depressed conical dimples, which enable a uniform plate pitch and an improved heat transfer coefficient. The height of these dimples can be varied during shop fabrication to establish the desired plate spacing necessary to meet your specific performance parameters. Prior to shipment, each module is leak-tested and rated for 0.05% maximum leakage at the design differential pressure, ensuring straightforward start-up and long service life. The rigid, heavy-duty frame assemblies may be parallel-bundled for additional capacity, and are easy to lift and install.
The MECS-ThermoZ™ Fully-Welded Plate Heat Exchanger design offers additional advantages over conventional heat exchangers:
当气体温度和露点条件要求最大限度地防止冷斑腐蚀时，Optimum-h™ 系统可提高冷凝应用附近的最低金属温度，并允许使用较便宜的结构材料。与大多数其他减少热交换器冷斑的尝试不同，Optimum-h™ 系统不会增加热流通过气体分离板的阻力，因此不会降低热交换器的整体效率。
