ANTSPACE PTC-R Pre-Heater Module

Description

ANTSPACE PTC-R Pre-Heater Module

Are you looking for a reliable heating solution designed for hydro-cooled Bitcoin mining infrastructure? The ANTSPACE PTC-R Pre-Heater Module from Bitmain is a specialized heating device designed to maintain stable coolant temperatures in hydro-cooling systems used in ANTSPACE mining containers. It ensures that the cooling liquid reaches optimal operating temperature during cold conditions, allowing hydro-cooled miners to start and operate safely in low-temperature environments.

The ANTSPACE PTC-R Pre-Heater Module uses PTC (Positive Temperature Coefficient) heating technology, which automatically regulates heating output to prevent overheating and improve safety. The module provides rated heating power of approximately 6 kW and operates on 380–420V AC three-phase power with 50/60Hz frequency, allowing it to integrate directly with industrial mining power infrastructure.

The heater draws about 8.7A current at 400V input and uses a pipeline-type PTC heating structure consisting of two 3 kW heating elements that warm the circulating coolant inside the container’s liquid-cooling system. The unit is designed to automatically stop heating when the coolant inlet temperature reaches 25°C, while an additional safety shutdown activates if the outlet temperature approaches 50°C, ensuring safe operation.

The module operates reliably in harsh industrial environments with a working temperature range of approximately -40°C to 50°C and supports coolant flow rates of around 10 L/min. It is designed with compact industrial dimensions of roughly 339 × 188 × 200 mm and a weight of about 11 kg, making it easy to install inside ANTSPACE container racks.

With its 6 kW heating capacity, automatic thermal protection, and integration into hydro-cooling circulation systems, the ANTSPACE PTC-R Pre-Heater Module helps ensure reliable startup and stable operation of hydro-cooled Antminer deployments in cold climates and industrial mining environments.
