Enabling Engineering Breakthroughs that Lead to a Better Tomorrow
Heatric’s Printed Circuit Heat Exchangers (PCHEs) are highly robust, compact plate-type heat exchangers. Due to the high pressure capabilities and high thermal effectiveness of PCHEs they are capable of operating outside the usual limitations of other plate type exchangers.
The unique construction processes involved in the manufacture of PCHEs means that they are ideally suited to high pressure, high temperature applications. These applications are traditionally serviced by shell and tube heat exchangers but Heatric’s PCHEs provide a much more compact unit with higher integrity.
The table below illustrates the typical characteristics and capabilities of diffusion-bonding. However, the design of every exchanger is bespoke, extremely versatile and dependant on customer specifications. As such, these figures are intended as a guide only.
| Unit weight range | 1 kg to 60 tonnes as a single unit. Although larger modular assemblies are possible. |
| Maximum design pressure | Current maximum design pressure is over 900bar (13,000 psi). |
| Design temperature range | Currently from 76K to 1255K (-320°F to 1,800°F), potentially as low as 2K (-450°F). |
| Maximum nozzle size | 1,200 mm NB (48 in NB) |
| Maximum surface area | 10,000 m 2 (108,000 ft 2 ) per PCHE |
| Typical area/unit volume | 1,300 m 2 /m 3 at 100 bar (400 ft 2 /ft 3 at 1450 psi) 650 m2/m3 at 500 bar (200 ft2/ft3 at 7250 psi) |
| Minimum temperature approach | 1°C (typically 3 – 5°C) 2°F (typically 5 – 10°F) |
| Heat exchanger effectiveness | up to 99% |
| Typical overall heat transfer coefficients | LP gas cooler 500 – 1,000 W/m 2 K (90 – 180 Btu/hrft 2 °F) HP gas cooler 1,000 – 4,000 W/m2K (180 – 700 Btu/hrft2°F) Water/water 7,000 – 10,000 W/m2K (1230 – 1750 Btu/hrft2°F) |
| Plate thickness | 0.5 mm (1) to 5.0 mm |
| Passage width | 0.5 mm to 5.0 mm (2) |
| Typical Reynolds number range | Gases: 1,000 – 100,000 Liquids: 10 – 5,000 |
(1) 0.2 mm for special cases
(2) >10 mm for non-semicircular passages
