OASE 51231 IceFree Thermo 330 Anti-Ice Heater

Product Overview

The OASE IceFree Thermo 330 (Model: 51231) is a high-efficiency anti-ice heater designed for outdoor water features. Its core function is to maintain an opening in the water surface during severe winter weather (down to –20 °C), ensuring gas exchange within the water body and thus safeguarding the health of fish and aquatic life. This device utilizes intelligent heating technology, activating only when a risk of freezing is detected, which greatly optimizes energy efficiency and avoids unnecessary power consumption in warmer weather.

This anti-ice device is particularly suitable for shallower ponds or external environments that experience prolonged freezing periods. It works by creating an ice-free zone around the float, maintaining a warmer area at the bottom to provide a comfortable temperature environment for the underwater ecosystem. For commercial or professional landscape maintenance clients who need to maintain winter pond aeration and prevent the buildup of harmful gases, the IceFree Thermo 330 offers a reliable and energy-saving winter protection solution.
