Our experience within the industry enables
us to provide customers with first class solutions. We are proud to boast a
fantastic team of highly qualified engineers who are able to provide solutions
to customers with all kinds of problems and requests. Our team uses state of
the art computer facilities and 3D CAD systems in order to provide complete and
accurate thermal and mechanical design, calculations and quotations from single
items through to large scale packages. Our specialists are able to respond
quickly to customers and provide all of the technical assistance that is
needed.

We have been designing and manufacturing heat
transfer equipment for more than 30 years and are well-respected for manufacturing
high quality, reliable equipment. We are widely associated by the production of
our TEMA and TEMA type tubular heat exchangers and can supply individual units
as well as to meet large scale contracts for new or expanding sites. Units
range from 100mm shell diameter up to 50 tonnes with mechanical design to
PD5500, ASME VIII Div 1, BS EN 13445 and Stoomwesen. Our wide range of items
such as heat exchangers, reactors, evaporators, columns, condensers, vessels
and receivers, enables customers to receive a complete service.

Air Cooled Heat Exchangers are becoming
increasingly popular in the industry and provide a cost effective solution in
most cases. We provide full thermal and mechanical design with vibration and
noise calculations along with high quality fabrication of induced or forced
draught heat exchangers. A choice of fan drives is available. Our Air Cooled Heat
Exchangers are fully welded, flanged and feature Plug type headers for use in a
wide operational pressure range of ASME, PED, and API specifications. Please
contact the team at Graham Hart for further information.

We have designed and manufactured various types of heat transfer equipment
Examples include:
* Heat Exchange Coils: designed for use in heat recovery applications, as
condensers, or for heating vessel contents.
* Fan Cooled Fin Tube Heat Exchangers and Condensers: supplied with fans or as
tube banks for outside installation.
* Double Pipe Counter Current Heat Exchangers
* Vegetable Oil Heater Units: supplied to the world-wide snack-food industry.

Here at Graham
Hart (Process Technology) Ltd we are also pleased to supply various industries
such as pharmaceutical, nuclear, and other sanitary applications with high
integrity and internally polished heat exchangers. This service may also employ
mechanical or electro polishing, special tube plate configurations, high
precision tube or tube-plate welding and special connections. Please contact the
team Graham Hart to find out more.
|
|
We also design
and manufacture various types of equipment such as distillation, adsorption,
separation and scrubber columns. We use state of the art computer technology
for vacuum or positive pressure and wind loading. Our team follows strict
quality control measures to ensure high accuracy during the manufacturing
process. It is essential that packing and tray supports are in the correct
position to guarantee the reliable performance of the column. Columns can be
supplied either as basic vessels ready to be fitted out, or with access
platforms, ladders, insulation, instrumentation, lighting and wiring.

We are proud of
our capabilities at Graham Hart (Process Technology) Ltd and have created a
number of custom-built packaged or skid units for various applications such as
heating, heat recovery, gas purification and anti biofouling for sea water
systems. Our highly experienced and skilled engineers work closely with clients
to product first class solutions for effective results. Examples of units that have
been tailored include heat transfer equipment, pressure and reactor vessels,
pumps, compressors, instrumentation and control, and more. This equipment has
served various applications in industries such as food, chemical, process and
offshore.
|
|
We are able to
manufacture small laboratory or pilot plant items through to full scale
production reactors featuring up to 12,000 litres capacity. Examples include
reactor vessels, pressure storage vessels, jacketed vessels, limpet coil
vessels, and catalytic reactors. These can be manufactured in materials ranging
from low temperature or carbon steel through to exotic nickel alloy types. We
operate the following codes: ASME U, ASME VIII Div 1, PD5500, BS EN 13445, and
Stoomwesen. Please contact our friendly team at Graham Hart (Process
Technology) Ltd with all enquiries.

With approximately 1250m sq floor space, our manufacturing department has a number of facilities including an area covered by craneage with an underhook height of over six meters, as well as separate areas for the fabrication of carbon and stainless steels. Facilities for drilling, machining and plate rolling are all available together with most welding techniques associated with pressure vessel production, including (but not limited to), Submerged Arc, MIG, MMA, TIG and Pulse MIG. Sophisticated automatic orbital welding equipment allows us to deal with Heat Exchanger Tube to tubeplate welding. In order to produce tube to tubeplate joints of a high integrity and consistency, this machine uses pre-set parameters and the TIG welding process.
