MONT HEX double-helix heat exchangers are designed for
heavy-duty biomass applications: high flows, up to 20%
total solids, low pressure drop and reliable 24/7
operation with proven CIP cleaning.
Proven double-helix technology for biogas plants: high
heat transfer efficiency, minimal fouling and stable
performance in thick biomass and demanding duty
conditions.
More than 800 HEX units installed on over 20 large-scale
biogas plants across Europe. Up to 80% heat recovery and
robust performance on manure, food waste, slaughterhouse
and agricultural residues streams.
In-house thermal design, heat balance calculations and
integration into your AD process. We optimise
configurations – horizontal or vertical, series or
parallel, carbon steel or stainless steel – for each
specific project.
Mont Stubline delivers the complete scope for HEX systems:
in-house design, dedicated production hall for serial
output, factory testing and on-site installation,
commissioning and long-term service support.
Transparent documentation, strict QA procedures and
long-term support – from 1:1 test plant development to
optimised operation on full-scale biogas plants worldwide.
Overview of double-helix layouts and process duties:
biomass/biomass and biomass/water heat exchange, tailored to
each AD plant and operating regime.
ENGINEERING
Development based on 1:1 test plant, field data from
large-scale biogas plants and close cooperation with leading
EPCs and operators in the AD industry.
MANUFACTURING
Dedicated HEX production hall, serial output of modules and
strict QA procedures – from material traceability to pressure
testing and final inspection.
INSTALLATION & SERVICE
On-site installation, commissioning and long-term service
support, including emergency stock units for quick
intervention and reduced downtime.
Double-helix heat exchanger system for liquid biomasses
ABOUT HEX
