GEA HeatWorks Industry Applications

Application-specific heat exchange solutions designed for the unique thermal challenges of each sector we serve.

Food & Beverage Processing

Heat exchangers are at the heart of food safety — pasteurization, cooling, CIP, and product-to-product heat recovery all depend on precise temperature control and hygienic design.

  • HACCP-compatible sanitary design with CIP-ready connections
  • Plate heat exchangers for rapid pasteurization with tight approach temperatures
  • Product-to-product regenerative heat recovery to reduce steam consumption
  • FDA-compliant materials including SS316L and food-grade gaskets

Pharmaceutical Manufacturing

Pharmaceutical processes demand absolute temperature precision and surface cleanliness that meets cGMP requirements. Our exchangers deliver both.

  • Precise temperature control within ±0.5K for reaction vessel jackets
  • Double-wall plate exchangers for critical barrier applications
  • Surface finishes to Ra ≤ 0.8 μm for cleanroom-grade installations
  • Full material traceability and 3.1 certificates per EN 10204

Heat Exchanger Selection: Key Trade-offs

Choosing the right heat exchanger type involves balancing multiple engineering and financial factors. Below are two common selection decisions and the trade-offs involved.

Plate vs. Shell-and-Tube Heat Exchangers

This is one of the most frequent engineering decisions in thermal system design. The choice depends on fluid properties, fouling tendency, pressure requirements, and available floor space.

Plate Heat Exchangers (PHE)

  • Heat transfer coefficient 3-5x higher than shell-and-tube due to turbulent flow between corrugated plates
  • Compact footprint — typically 20-30% of the floor space required by an equivalent shell-and-tube unit
  • Capacity expansion by adding plates without replacing the frame
  • Lower fluid hold-up volume, reducing refrigerant charge in DX applications

Shell-and-Tube Heat Exchangers

  • Handles design pressures above 25 bar and temperatures exceeding 300°C where gasket materials limit PHE use
  • More tolerant of fouling, particulates, and high-viscosity fluids — longer intervals between cleaning
  • Preferred for steam heating applications and condensation duties
  • Typically longer service life in heavy-duty chemical and petrochemical environments

Selection guidance: For clean-fluid HVAC and food processing duties below 25 bar, plate exchangers typically deliver lower lifecycle cost. For high-pressure chemical processes, high-fouling duties, or steam applications, shell-and-tube remains the preferred choice.

Natural vs. Synthetic Low-GWP Refrigerants in Heat Exchanger Design

The EU F-Gas Regulation (revised 2024) and Kigali Amendment are accelerating the phase-down of high-GWP HFC refrigerants. Heat exchanger specification must account for the refrigerant choice early in the design process.

Natural Refrigerants (CO2, NH3, Propane)

  • GWP of 0 (NH3) to 3 (R-290), future-proofing against further regulatory tightening
  • No patent dependencies — long-term cost stability
  • R-744 (CO2) transcritical systems require exchangers rated for 90-130 bar operating pressure
  • R-717 (ammonia) requires steel construction — copper and copper alloys are incompatible

Synthetic Low-GWP HFOs

  • Drop-in or near-drop-in compatibility with existing HFC infrastructure, reducing retrofit costs
  • No flammability concerns (A1 safety class for many blends) vs. A2L/A3 classification of naturals
  • Familiar service procedures for existing technician workforce
  • Higher refrigerant cost per kg and potential long-term PFAS regulatory exposure

GEA HeatWorks designs exchangers compatible with both pathways. For new-build projects, natural refrigerants often offer the lowest 20-year total cost of ownership. For retrofits with budget constraints, HFO blends can extend equipment life while reducing GWP by 50-75% vs. legacy HFCs.

Application Boundaries and Considerations

Transparent engineering means acknowledging where our equipment performs at its limits. The following factors should be considered during heat exchanger specification.

Pressure and Temperature Boundaries

Gasketed plate heat exchangers are limited to approximately 25-30 bar and 180°C by gasket material properties (NBR, EPDM, Viton). Applications exceeding these limits require welded plate or shell-and-tube construction at higher cost and longer lead times.

Fouling and Particulate Sensitivity

Plate exchangers with narrow channel gaps (2-5 mm) are susceptible to blockage from fluids containing suspended solids above 300 μm or high fiber content. Pre-filtration or strainer installation is required for such applications, adding to system cost and maintenance scope.

Minimum Order and Lead Time Constraints

Custom-engineered units in exotic alloys (titanium, Hastelloy, super duplex) carry minimum order values and lead times of 14-22 weeks due to raw material procurement. Standard stainless steel plate frames ship in 4-6 weeks, but capacity during peak season (Q2/Q3) may extend by 2-3 weeks.
