AKT Heat Exchanger

Technical Specifications of AKT Heat Exchanger(Based on TEMA Naming Convention)

t should be noted that "AKT" is not an official TEMA designation. In industry practice, AKT typically refers to an Accessible Kit Type heat exchanger, which is a specially designed plate-shell or compact heat exchanger combining the high efficiency of plate heat exchangers with the pressure resistance of shell-and-tube exchangers. Below are the technical parameters:

1.Naming Convention Analysis (Industry Practice, Non-TEMA Official)

o A: Front Head Type (A = removable flat cover for maintenance access).
o K: Shell Type (K may represent "Kit" or "Compact", indicating modular compact design).
o T: Rear Head Type (T may denote "Thermal" or "Turbulent", emphasizing high-efficiency heat transfer design).
o AKT is not a standard TEMA code but a customized name used by end user for accessible kit-type exchangers.
o Its design combines features of TEMA A-type front head (removable cover) and F-type shell (double-pass or compact).

2.Key Technical Parameters (Based on Compact Accessible Design)

Parameter	Typical Value/Range	Remarks
Design Standard	ASME VIII Div.1 / TEMA / EN 13445	Requires special evaluation
Heat Transfer Area	10~1000 m²	Modular plate or compact tube bundle
Design Pressure (Shell/Tube Side)	0.6~6.4 Mpa (6~64 bar)	Fully welded or partially removable
Design Temperature	-50°C to +400°C	Special materials for high-temp. models
Plate/Tube Material	SS316L / 254SMO / Titanium	Corrosion-resistant, thin plate/small tube
Channel Spacing	3~8 mm	Narrow channels enhance heat transfer
Heat Transfer Coefficient	2500~6000 W/(m²·K)	2~4× higher than shell-and-tube
Pressure Drop (per side)	≤60 kPa	Low flow resistance design
Connection Standard	ANSI / DIN / GB Flanges	DN50~DN600

3. Structural Features

o Removable Plate/Tube Bundle: Front flat cover (A-type) can be opened for partial or full bundle removal and cleaning.
o Compact Shell: Volume is 1/3~1/5 of traditional shell-and-tube exchangers.
o Multi-Pass Configuration: Both shell and plate/tube sides can be multi-pass (e.g., 2/4 passes).
o Anti-Fouling Design: Narrow channels + high turbulence reduce fouling deposition.

4. Typical Applications

o Petrochemicals: Natural gas processing, solvent recovery
o Pharma/Food: CIP/SIP systems, high-sanitation applications
o Power Industry: Waste heat recovery, closed-loop cooling
o Marine Engineering: Compact central cooling systems

5. Data Required for Selection

o 1.Fluid Properties (viscosity, corrosiveness, solid content, fouling tendency).
o 2.Temperature/Pressure Curves (including transient conditions).
o 3.Allowable Pressure Drop (affects channel design).
o 4.Cleaning Frequency (determines need for removable structure).

6. Comparison with TEMA Standard Types

Feature	AKT Exchanger (Compact Accessible)	TEMA AES (Floating Head)	TEMA BEM (Fixed Tube Sheet)
Structure	Removable plate/compact tube + removable front cover	Removable tube bundle + packed floating head	Fixed tube bundle + removable front cover
Heat Transfer Efficiency	High (narrow channel turbulence)	Medium-high (baffle-dependent)	Medium (fixed tubes)
Pressure Rating	≤6.4 Mpa	≤6.4 Mpa	≤15 Mpa (high thermal stress)
Maintainability	Mechanically cleanable (partial/full removal)	Mechanically cleanable (tube bundle removable)	Tube side cleanable, shell side difficult
Cost	Medium-High	Medium	Low

Note: AKT exchangers are often custom-designed by manufacturers. Directly provide operational requirements to manufacturers Wuxi Yiteng for selection.
