PANEL WORLD
Panel World specialises in the design , manufacture and installation of high quality , modular cold and freezer rooms , cold stores , hygienic preparation areas , chicken houses and many more solutions to suit your insulated panel needs .
Panel World now manufacturers from the first ultramodern , dis-continuous polyurethane panel plant in the Southern Hemisphere :
• Polyurethane panels are extruded through a vacuum
• Cyclo Pentane is used as blowing agent
• The combination of vacuum technology and Pentane increases the panels ’ mechanical strength by an estimated 30-40 % and a 5-10 % improvement in insulation
• Pentane is a natural substance and is 100 % ozonefriendly
• UNIDO contributed towards the development of the plant

PERISHABLE PRODUCTS EXPORT CONTROL BOARD ( PPECB )
The Perishable Products Export Control Board ( PPECB ) is an independent service provider of quality certification and cold chain management services for South African producers and exporters of perishable products . The PPECB is constituted and mandated in terms of the PPEC Act No 9 of 1983 to perform cold chain services . The PPECB also delivers inspection and food safety services under the APS Act No 119 of 1990 .
PPECB inspectors , stationed across South Africa , deliver end-point inspection services on over 200 perishable product types destined for export at over 1 500 locations . In addition , the PPECB is also responsible for South Africa ' s cold chain management and ensuring that products for export are handled , stored , and transported at specific temperatures and optimum conditions . Cold chain services provided by the organisation include the inspection and approval of equipment such as containers , specialised reefer vessels and cold stores ; overseeing loading processes and en route temperature management of produce .
Ensuring food safety is also high on the PPECB ' s list of strategic focuses . Ultimately the PPECB ensures that Food Business Operators ( FBOs ) comply with the standards regarding food hygiene and food safety of regulated agricultural food products intended for export .
RICKARD AIR DIFFUSION
Rickard ’ s Multi-Zone Fan Coil Unit Controller is much more than a traditional FCU controller . As the name suggests , the controller can be combined with Rickard ’ s VAV diffusers so that multiple zones can be controlled without the need for pressure sensors or dampers .
Since the FCU and diffusers are linked through the tried and tested MLM system , it can regulate fan speed and hence duct pressure by monitoring the diffusers damper position .
The benefits of a Mullti-Zone FCU controller over a traditional constant volume diffuser FCU system are as follows :
• Zones with different loads can be ducted to the same FCU .
• Every zone and occupant can be kept comfortable .
• Larger FCU ’ s can be selected to supply multiple zones and therefore reduce the system cost . Fan speed can be matched to diffuser demand , creating excellent circulation and the absence of dumping at low fan speeds .
• To conserve energy , the Multi-Zone Fan Coil Unit Controller can power down the Fan Coil Unit if the room is unoccupied or if a window or door is opened .
• By adding an iPSU , power and BMS connectivity can be added .
With Rickards Multi Zone FCU Controller , zones will never be over- or underconditioned again .
