Typical Industries Include:

Brazed Plate Heat Exchangers

APV standard ‘P’ types offer AISI 316 stainless steel plates and connections with copper brazing. The units are rated for 450 psig/31 bar operating pressure with a maximum temperature of 437°F/225°C. P series are typically installed with a Y-strainer to protect the unit from debris, while custom insulation kits minimize ambient losses.

A principal system design includes a primary heat source (i.e. boiler) and a secondary loop such as snowmelt or radiant circuit. Sanitary instant hot water can also be produced from this system with the use of appropriate controls. Due to the low internal volume of the brazed exchanger, instant hot water is possible in many cases eliminating the need for thermal storage tanks.

Inherent of their turbulent flow, brazed plate heat exchangers resist particulate fouling and scaling. Units can be cleaned using a phosphoric or citrus acid solution circulated in reverse at 1.5 times the normal fluid flow rate. Replacing bulky shell and tube, coiled, coaxial and other less efficient heat exchangers, brazed plates have allowed system designers not only to think outside the box, but also to make the box smaller – pushing the boundaries of system design

Fully Welded Heat Exchanger

Scraped Surface Heat Exchangers

The APV scraped surface heat exchangers (SSHE) consist of a jacketed cylinder with a rotating dasher holding rows of scraper blades. The product is pumped through the cylinder while the heating or cooling medium is circulated between the cylinder and the jacket. The medium can be steam, water or a refrigerant such as ammonia or freon.

Product Range

No matter what specific operational requirements a customer has, SPX can match them to a scraped surface heat exchanger. A large number of options are available so that each machine can be carefully tailored to the application. This array of alternatives includes:

  • Traditional horizontal configurations as well as vertical designs to save floor space
  • Special seal assemblies to handle everything from industrial to aseptic processing applications
  • Dasher types for each different product’s processing characteristics
  • Scraper blades in a variety of materials including high temperature plastics or stainless steel
  • Corrosion-resistant cylinders in several metallic compositions
  • Full-flow door designs for viscous and particulate products
  • An integral refrigeration system for cooling applications
  • A choice of variable speed or fixed speed drives in a wide range of horsepowers
  • Down-sized models for laboratory pilot plant or small runs


  • Able to heat and cool fluids with particulates up to 32mm
  • Able to heat and cool high viscosity fluids
  • Easy to open for inspection

Plate Evaporators

During the plate evaporation process, liquid is pumped between thin plates with the heating medium on the mating surfaces. The product is then evaporated with the vapor generated forming a high velocity core. This expansion in volume causes a high-velocity, thin film on the heat exchange surface providing efficient heat transfer.

Plate evaporators should be considered for applications that have:

  • Capacities up to 27,000 kg/h water removal
  • A need for future expansion
  • Limited head space
  • A particle size smaller than 600 Micron.

Product Range

Rising/falling film plate evaporators
The original plate type evaporator, the Rising/Falling Plate system is a flexible, multi-duty unit engineered to handle medium size production runs of heat sensitive products. Most are used by fruit juice and other food processors where low residence time and 104°F to 203°F ( 40°C to 95°C) operating range temperatures are essential for the production of quality concentrate. In increasing numbers, many are being used in pharmaceutical and chemical plants for antibiotics and inorganic acids. To permit relatively high concentration ratios to be carried out in a non-recirculatory, single pass flow, these evaporators may be designed as multi-effect and/or multi-stage systems. Water removal capacities range from 500 to 15,000 kg/hour. For much smaller production or pilot plant runs ranging from 50 to 700 kg/hour a "Junior" plate evaporator is offered. This packaged system can be provided as a single effect unit requiring only 3.5 m² of floor space or with multiple effects for larger operations.

Falling film plate evaporator 
Combining all the advantages of the original Rising/Falling Film Plate Evaporator with the added benefits of even shorter product residence time and larger capacities, the APV Falling Film Plate Evaporator is widely used by many processors. With its larger vapor ports, evaporation capacities typically are up to 20 to 27,000 kg/hour of water removal. Furthermore, residence time is about 25% shorter, providing even greater assurance of protection against thermal degradation.

The APV Paravap is specially designed to process high solids concentrates or those having non-Newtonian viscosity characteristics. Operating advantages include low rates of fouling and minimal product residence time to protect against thermal degradation. Unlike wiped film evaporators, this unit has no moving parts, reducing both capital and operating costs. Under normal operation, feed liquor and the heating medium are directed to alternate passages formed by the positioning of heat transfer plates within the evaporator. As the feed contacts plates heated by steam or hot water, boiling occurs. Small plate gaps and corrugated plate patterns create high vapor velocities and turbulence which result in a very high rate of heat transfer. The liquor is vaporized, and the concentrated product and vapor are discharged to the separator.

For products which tend to crystallize during concentration or those that contain a high percentage of suspended solids, SPX offers the APV Paraflash. This compact unit combines a plate heat exchanger, an external separator, and a vacuum system. It is designed to operate as a forced circulation, suppressed boiling evaporator. By using liquid static head above the heat exchanger or a special orifice piece in the discharge line, vaporization is arrested until the product liquor flashes into the separator. Any crystallization then occurs and a suspended slurry results. High liquid velocity flow combined with induced turbulence deters scaling on heat transfer surfaces, and promotes longer production runs.


  • Improved product quality. The short heat contact period resulting from single pass operation and low liquid holdup eliminates product deterioration even when highly heat sensitive liquids are involved. The resulting concentrate is of the highest quality possible.
  • Higher product concentration. The variety of plate evaporators available from SPX allows custom concentrates to be produced. Ninety seven percent total solids or better are possible depending on feed material characteristics.
  • Low liquid holdup. Very little product is actually in the plate evaporator at any time. This permits rapid start-up and shutdown with minimal waste. Small quantities of product may be processed economically.
  • Easily cleaned. All stainless steel surfaces within the plate packs are fully accessible for easy cleaning. Normal CIP is done with low consumption of cleaning chemicals due to the low liquid holdup.
  • Flexible capacity. By simply adding or removing plate units, varying evaporation rates may be achieved. Large expansions are possible with additional frames and plate units.
  • Low installation costs. Due to the compact size and low weight, no cranes or special foundations are required for installation. Typically, an existing building on site is suitable and installation time is minimal.

Heat Exchangers

The History:

The first commercially successful plate-and-frame heat exchanger in the world was introduced in 1923 by Dr. Richard Seligman, the founder of the Aluminum Plant and Vessel Company Ltd., commonly known today as APV. The very first Paraflow Plate and Frame Heat Exchanger was constructed of cast gunmetal plates and enclosed within a frame that set the standard for today’s computer-designed thin metal plate heat exchanger known around the world.

Heat Exchangers Functions

Heat Exchanger Function:

A plate heat exchanger is a unit which transfers heat continuously from one media to another media without adding energy to the process. The basic concept of a plate and frame heat exchanger is two liquids flowing on either side of a thin corrugated metal plate so heat may be easily transferred between the two. The plate heat exchanger efficiency requires less floor space compared to other types of heat transfer equipment and is lighter in weight.
