COAXIAL HEAT EXCHANGER
The coaxial micro heat exchanger consists of concentric tubes in which a
fluid streams in a counter current configuration. In order to transfer heat to
and from this fluid, a heat transfer medium
streams in separated channels
along the concentric tubes in the core as well as in the outer region of the
module.
The module can be completely disassembled so that cleaning is easily
possible if plugging of the concentric fluid channels should occur. In addition,
the characteristic dimensions of the fluid duct are larger than in standard platetype
micro heat exchangers and the device has been successfully used for
particle loaded or highly viscous fluids.
As a matter of fact, the heat transfer rate per unit volume is smaller than
that of plate-type micro heat exchangers. Nevertheless, a heat transfer rate of
typically more than 100 W is achievable which is sufficient for many
applications of the microreaction development platform. Because of their
comparatively small pressure losses, coaxial heat exchanger modules can be
operated in series. This allows enhancing the heat transfer rate and, in
particular, to realize a predetermined temperature profile along the flow
direction of a reacting fluid which is beneficial for special chemical
transformations.

CENTRIFUGAL SCREENERS AND FLLUID BED DRYERS
The Kason Centri-Sifter® is a versatile, high capacity, compact and economical centrifugal sifter used for screening a wide variety of powders or granular materials, including chemicals, plastics
and resins, foods, dairy products, pharmaceuticals and biologicals. This equipment is the ideal choice for continuous scalping of dry or moist materials, even those that tend to ball or agglomerate as these units delump and deagglomerate while screening. The Centri-Sifter Screener is also extremely effective as a liquid/solids separator.
Broad model range solves specialized problems
Centri-Sifter centrifugal sifters are designed for gravity-fed applications, and for sifting in-line with pneumatic conveying systems. They are available as single and twin models and low profile units, and offered in a broad range of standard, modified, and custom configurations. All are available with belt drive or direct drive. Units may be free-standing or adapted for easy mounting on new or existing process equipment. On gravity-fed models, a large access door allows inspection and cleaning. In-line pneumatic units offer large ports for inspection. Removable end housings allow rapid cleaning and screen changes. Centri-Sifter separators meet the most stringent worldwide sanitary standards including USDA, FDA, 3-A, and BISSC. Special finishes and materials also make these sifters suitable for biochemical and pharmaceutical applications.
Screen options
The choice of separating media includes nylon and other monofilament cloth, woven wire in selected metals, perforated plate screen, and wedge wire. Wedge wire screens are preferred when sifting large, dense particles with angular shapes, oversize lumps or when it is important that contaminating debris must be prevented from entering processing streams. Kason's wedge wire screens are rugged, durable and provide a high degree of on-stream reliability.
Anti-blinding devices speed production, reduce maintenance
Kason offers a variety of devices that increase production by combating screen blinding. These devices reduce the clearance between the rotating paddle and the cylindrical screen without contacting or abrading the screen. Narrowing the gap between the rotating element and the screen surface enhances screening rates under near size conditions, thereby increasing throughput.
Features:
* Dust-free, sanitary operation. Approved for use by USDA, FDA, BISSC, 3-A and other U.S. and European regulators
* Quiet, vibration-free action
* Quick screen change: 2 minutes or less
* Easy clean-out
* Double seal outboard bearings
* Rapid sieving action
* Heavy duty construction for continuous operation
* Compact design
* Low power requirements
* Integral cleaning/ inspection door
* Many sizes and single or twin models, including belt-driven units with motors ranging from 1hp (.75 kW) to 5hp (3.75 kW) and direct-driven units with motors ranging from1 hp (.75 kW) to 3 hp (2.25 kW)

THE BENEFITS OF THE BOILER MANAGER

- or oil-fired boilers

HOW DOES THE BOILER MANAGER WORK?
A typical boiler system
Boilers are unintelligent and often fire up unnecessarily, when there is still sufficient heat within the system. When this happens the boiler is re-heating water that is sufficiently hot and the excess heat is wasted up the boiler flue; this is called dry cycling. In a typical system, the boiler is designed to work most efficiently with an 11°C difference between the flow and return water temperatures (e.g. out at 66°C and back at 55°C). The boiler setting is fixed and usually set to cater for the coldest external temperatures.
A system controlled by The Boiler Manager
Anti-cycling technology is well established in the large commercial boiler market place, but the Boiler Manager is one of the first systems to successfully apply this technology at a price that makes it viable for domestic or small commercial boilers. In contrast with a typical boiler system, the Boiler Manager is a much more efficient energy saving system.
The Boiler Manager is wired between the time clock and the room thermostat, with sensors on both flow and return pipes, and takes over the management of the boiler to run it more efficiently. It has high performance microprocessor control and its own exclusive software, which was written specifically to overcome the shortcomings of existing boiler control unit technology as identified in numerous Building Research Establishment (BRE) reports. The Boiler Manager is not controlled by time, but by temperature, and so is able to prevent dry cycling without loss of comfort.
The Boiler Manager monitors flow and return and varies the threshold settings and firing cycle in order to achieve genuine energy saving. The return temperature is used to determine when to reduce the boiler setting and when to extend the firing cycle, without affecting comfort levels. The Boiler Manager will not allow the boiler to fire up until the return temperature has dropped fully to the required temperature. It is a basic principle of Thermodynamics, that if the return temperature is reduced, then the boiler heat exchanger will operate more efficiently, therefore being a more efficient energy saver.
The charts below monitor the running of a typical domestic boiler with and without the boiler manager controlling the system. Two conclusions are immediately evident:
- The boiler fires 17 times in a minute period without the boiler manager and 7 times with the boiler manager.
- The Boiler Manager ensures that the boiler is operating precisely to the set demand temperature of 66 degrees Celsius, without loss of comfort; this is very different to the situation without the Boiler Manager, where the system temperature is at 78 degrees Celsius, resulting in dry cycling and wasted heat.

SERIES DR DEHUMIDIFYING DRYERS
Drying of Engineering Polymer Granules and Regrind
DESCRIPTION
The DR range of Dehumidifying Dryers is fully
automatic, single-desiccant cartridge design,
available in 2 models with throughputs up
to
50 kg/hr.
The Drying Hoppers are fully insulated, have
high-efficiency diffusers, sight-glass, drain-
out, shut-off slide and hinged cover with
universal mounting for a hopper loader. They
are available in sizes up to 300 litres capacity.
The system is complete with hoses etc. and
may be mounted on the machine-throat or on
a portable floor-stand.
Jenco offers a wide range of Multi-Hopper and
other custom arrangements to suit specific
requirements.
We also offer a full range of Automatic
Hopper Loaders, including Quick-Material-
Change Systems.
OPERATION
The integral side-channel blower generates
high pressure air-flow through the desiccant
cartridge, through the process heater and
into the drying hopper. The air diffuses
through the material and exhausts via the top
of the drying hopper, through a large-area
cartridge filter and back into the blower.
After a preset timed period, the blower
reverses and regenerates the desiccant bed.
The direction of air-flow is controlled by non-
return valves and does not require the use of
a spool valve. The controls provide digital
setting and display of process temperature
and include an overtemperature alarm. Also
included are indicator lights showing system
status and an alarm for blocked filter.
Fully Automatic
Dew-Point down to –40oC
Stainless Steel, High-Efficiency Drying Hopper
Long-Life Desiccant Cartridge
No Compressed Air required
Large-Area Return-Air Filter
Machine or Floor Mounted
Customised to suit
Special Requirements
