Model DST-4
Street Sweepers / Regenerative Air Sweepers
Tymco
The TYMCO Model DST-4® is a mid-sized, dustless street sweeper that combines the proven technology of TYMCO's Regenerative Air System with a patented filtration system. This system captures a minimum of 95% of 0.30 micron and larger size particles, far exceeding PM₁₀ requirements. Designed for efficiency in both wet and dry conditions, the DST-4 ensures optimal performance without the need to avoid puddles or adjust operations based on weather. Mounted on a highly maneuverable cabover standard truck chassis, it offers the versatility needed for various municipal and industrial applications.
Features
Pick-Up Head: Incorporates a full-width 78-inch blast and suction, designed to work effortlessly with the TYMCO Regenerative Air System to pick up a wide variety of debris, including ultra-fine particles.
Hopper: Features a high dump function that lifts the hopper up to 72 inches, allowing dumping into various size containers, including most 30 cubic yard roll-off containers. Equipped with powerful piggyback hopper lift cylinders and a permanently attached safety strut for easy accessibility.
Gutter Brooms: Equipped with 36-inch diameter gutter brooms with in-cab controls, allowing the operator to control the speed and tilt of the brooms to reach into the deepest gutters. A pressure sensing sequence valve automatically determines the digging pressure needed for different debris, maximizing broom bristle life and cleaning performance.
Variable Speed Gutter Brooms: From inside the cab, the operator can control the speed of the gutter brooms, matching the speed of the truck while sweeping to reduce dust generation.
Dust Control: Incorporates a high-efficiency multi-pass cylindrical centrifugal dust separator for maximum particulate separation and sweeping performance. Designed for easy clean-out and maintenance. Onboard 77 gallons of water are available for dust control around the gutter brooms and inside the hopper. In below-freezing conditions, the sweeper continues dustless operation without using water.
DST System: The diverted air is filtered through TYMCO’s patented DST system, which includes a pre-cleaner and cartridge filters with a Minimum Efficiency Reporting Value (MERV) 16 Rating, capturing a minimum of 95% of 0.30 micron and larger size particles. Both the pre-cleaner and cartridge filters are washable, ensuring long service life. The system operates efficiently in wet or dry conditions without operator adjustments.
Power Unit: Powered by a 56-horsepower Kubota auxiliary engine that drives all hydraulic functions through a gear-driven pump and directly belt drives the blower wheel.
Blower Wheel: Utilizes a natural rubber-coated aluminum blower wheel, which is abrasion-resistant and reduces fuel consumption due to its lightweight design.
Rear View Camera: A rear view back-up camera with an in-cab display allows the operator to view the area behind the Model DST-4 while backing up, providing additional safety and peace of mind. Additional cameras are available to view the pick-up head and gutter brooms.
