With Delta T Thermal Solutions, customers find efficiency, versatility, quality construction, and extensive knowledge of heat exchange technology and products. Delta T Thermal Solutions is your global solutions provider for all your heat transfer needs.

PLATECOIL®

Delta T Thermal Solutions PLATECOIL® is a very efficient and versatile light-duty plate-type heat exchanger. Its unique construction enables high heat transfer efficiency for heating and cooling, which can be applied to a wide range of applications. Units are commonly used in the plating, metal finishing, chemical processing, pulp & paper, waste treatment, textiles, pharmaceutical, and food & beverage industries.

PLATECOIL® is fabricated from two sheets of metal using a fully computerized welding machine that uses electric roll spot resistance welding. The plate is then hydraulically inflated, forming a variety of flow patterns. Each ECONOCOIL® plate is designed and constructed to match the needs of each application and requirement.

PLATECOIL® units are usually constructed out of carbon steel, 304 and 316 stainless steel materials. Other materials we do offer are monel, inconel, hasealloy, alloy 20cb-3, 254-SMO, AL6XN, and titanium. 

Multi-zone PLATECOIL® units are ideally used when steam is heating the medium. With its zoned header design, Multi-Zone PLATECOIL® provides far more heat transfer efficiency than pipecoil or units with straight headers in applications requiring the use of steam. The Multi-Zone headers and flow arrangement provide controlled distribution of the steam as it flows through the PLATECOIL®. The rate of condensate removal from the passages or passes is significantly increased as compared to units with straight headers. Efficiency reducing condensate blocking is minimized. As a result, Multi-Zone PLATECOIL® provides faster heat-up and better heat transfer rates.

Serpentine PLATECOIL®: with a Serpentine flow configuration provides outstanding performance with liquid heating or cooling media, because its configuration allows high internal flow velocities to be achieved. As a result, high heat transfer rates can be obtained. Serpentine PLATECOIL® is frequently specified for use with cold water, high temperature hot water, hot oil and refrigerants. When used with refrigerants, the Serpentine flow design offers the additional advantage of eliminating the possibility of “short-circuiting”.

Both Multi-zone PLATECOIL® and  Serpentine PLATECOIL® styles available in over 300 standard sizes. Widths range from 12″ to 43″. Lengths range from 23″ to 143″. Custom units for your specific application are available in many sizes and material configurations. This can be paired with any of our accessories such as handles, hangers, lugs, or special connections.

MAXCHANGER ®

MAXCHANGER® single- and multiple-pass designs fit virtually any application requirement. The unique geometry of the patented MAXCHANGER®’s variable interspaces produce extremely high “U” values. Channels formed between the specially dimpled, welded plates direct the two heat transfer media counter currently through alternate paths for maximum efficiency, immediate thermal response and a close temperature approach capability of less than 1°C (2°F).

The corner angle fittings or corner half-pipe fittings, enable inlets and outlets—NPT or flanged—to be located in any number of configurations for maximum flexibility in tight spaces.

The 1-mm (0.039-in.) thick dimpled heat exchanger plates are sandwiched between top and bottom plates specified to withstand the design pressure. Special spacers separate the plates, isolating the channels and establishing countercurrent flow. Four corner angles (or half-pipes) are welded to side plates, top and bottom plates and to the heat exchange plate points, forming inlet and outlet headers.

One of the best benefits of ECONOCOIL® is that it can be produced in an extensive range of custom-made variants when needed for special applications. For example, Delta T Thermal Solutions can alter the connection location and length, creating an irregular-shaped curved ECONOCOIL® to fit a tank cone end. Another application example is Delta T staff can weld several plates together to form banks which can be used for large heat exchanger duties and provide accessories to assist with installation and maintenance.

There are two main types of ECONOCOIL®, which determine the unit’s structure. These are double embossed and single embossed.

 

 

Double Embossed ECONOCOIL®

Single Embossed ECONOCOIL®

Delta T Thermal solutions can manufacture ECONOCOIL® in a massive variety of shapes and sizes to suit all purposes. There are five basic styles to fit specific applications, with all styles available in double and single embossed forms in numerous configurations. All units are supplied with BSPT Male Threaded Connections as standard. However, we can provide a variety of connection options. For Styles EC70, EC80 & EC90, the connection size depends on the plate dimensions.

Delta T Style EC50

Style EC50 ECONOCOIL® is largely used for heating and cooling while immersed in tanks. Therefore, its design is most suitable for liquid-to-liquid duties such as heating oil with hot water. Easy lift handles can be attached with hangers available to make installation alongside a tank wall as simple as possible.

Delta T Style EC60

Style EC60 ECONOCOIL® is widely used for high-velocity media to generate a high-pressure drop which gives accelerated heat transfer. It is commonly used with water, hot oil, and direct expansion refrigerants. Handles can be attached along the width to allow tank immersion.

Delta T Style EC80

Style EC80 ECONOCOIL®’s primary use is for external Clamp-On ECONOCOIL® for maintaining applications. It’s predominantly effective with high flow rate fluids as it creates minimum pressure drop. Clamp-On EC80 Econocoil units are normally supplied with attachment lugs and heat transfer mastic.

ECONOCOIL® Accessories & Options

With each ECONOCOIL®, Delta T Thermal Solutions can offer a range of options and accessories to assist Installation and improve performance. For ECONOCOIL® to be used in tanks, we offer handles and hangers so they will be correctly positioned and can easily be inserted and removed. For clamp on applications, we offer Konduct No.1 Heat Transfer Cement to assist with heat transfer. Additionally, we supply lugs with tie bolts to securely fasten the ECONOCOIL® to surface sides.
