The Vaisala Triton Mirror Heater System is a propane‑fueled catalytic heater that keeps the Triton sound mirror free of snow and ice.
The Vaisala Triton Mirror Heater System uses a propane‑fueled catalytic heater to warm circulating antifreeze, preventing snow and ice from accumulating on the Triton aluminum sound mirror. The heated antifreeze is pumped through tubes behind the mirror in a radiator‑style design, eliminating open flames.
Key specifications include aluminum, EPDM and nylon plumbing; environmentally safe propylene glycol antifreeze rated to –73 °C burst and –50 °C freeze protection; LPG (propane) fuel with a consumption of 5.4 fl oz (160 ml) per hour; capacity for one 30‑lb and one 40‑lb cylinder; up to 200 hours of operation with 70 lb of fuel; average power draw of 10 W during snowy season; a 5‑minute pre‑heat cycle; and mirror heating to approximately 20 °C at 0 °C ambient.
