Winona, MN, USA - May 27, 2009 - Italian manufacturer MAC3 Water Systems, a world leader in developing products for the flow control industry, has developed the Mac3 level regulator, or float switch, with the help of flame retardant materials from custom compounder RTP Company. The float switch allows level-controlling and monitoring equipment, such as pumps, valves, or alarms, to automatically start and stop when a specified fluid level has been reached.
"The Mac3 regulator features a waterproof float equipped with an inner micro-switch connected to the cable," explained Lorenzo Ronchi of MAC3 Systems. "The float's orientation depends on the liquid level and determines the attitude of the micro-switch, which controls the pump operation. The pump is automatically switched on and off, providing both overflow and dry running protection."
The regulator's design, which includes a protective double-walled waterproof chamber, ensures maximum reliability of the mechanism. Engineers designed the shape of the float switch to be completely smooth, making it virtually impossible for solids to collect on its surface and disrupt performance. Its rounded shape makes this device suitable for a variety of environments, particularly waste systems.
Due to its potentially destructive surroundings, the float's outer casing required a flame retardant compound with both high impact values and UL approval. MAC3 Systems selected an RTP 100 Series flame retardant polypropylene compound for the casing, which is UL94 recognized with elevated RTI ratings. This compound's excellent impact resistance, combined with resistance to common chemicals, protects the float switch from damage and ensures consistent functionality.
"The most significant benefit of the Mac3 regulator is its high reliability," said Ronchi. "This is due to the use of high quality materials, strict manufacturing procedures, and extensive testing. RTP Company also greatly contributed to the product's reliability by providing excellent service and material recommendation, ensuring the best possible results and making it easy for our engineers to develop a successful product."
