Mac3 uses RTP fire-proof materials in float switch

Italian manufacturer Mac3 Water Systems has developed the Mac3 level regulator, or float switch, with the help of flame-retardant materials from RTP.
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.
Lorenzo Ronchi of Mac3 Systems said 'The Mac3 regulator features a waterproof float equipped with an inner micro-switch connected to the cable.
'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.
Engineers designed the float switch to make it 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.
Because of its potentially destructive surroundings, the float's outer casing required a flame-retardant compound with high impact values and UL approval.
Mac3 Systems selected an RTP 100 flame-retardant polypropylene compound for the casing, which is UL94 recognised, 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.
