BT4-0112 A/C Accumulator – Volvo Mobile Air Conditioning

Description

The BTRAC BT4-0112 A/C Accumulator plays a critical role in mobile A/C system reliability. It controls refrigerant flow before vapor returns to the compressor. At the same time, it captures moisture and excess liquid refrigerant. As a result, it helps prevent compressor damage and supports consistent cooling.

Accumulators should be replaced whenever technicians open the A/C system or replace major components. Because moisture and liquid refrigerant can cause internal damage, timely replacement remains essential. Therefore, the BT4-0112 helps restore proper system protection after service or repair work.

Heavy-duty HVAC systems often operate under vibration, heat, and long duty cycles. Because of these conditions, dependable refrigerant management matters. The BT4-0112 provides that protection while remaining compatible with common Volvo mobile A/C architectures.

Based on validated interchange usage, this accumulator is commonly used in Volvo on-highway and vocational vehicle HVAC systems, making it a dependable service-replacement option.
