CONSOLIDATE condensate DRAINAGE LINES with A flexible multi-line TANK solution
The MultiTank™ mounting accessory is specifically engineered for seamless integration with BlueDiamond’s MegaBlue® and MaxiBlue® condensate pumps. Designed to address spatial limitations and streamline multiple condensate drainage lines into a single collection point, the MultiTank simplifies complex HVAC installations—making it particularly well-suited for ceiling-mounted units or remote locations. Capable of handling up to six independent condensate drain lines, it offers a highly efficient, low-maintenance alternative to traditional float switches and tank pumps. With no moving parts to clog or seize, the MultiTank ensures reliable, long-term performance in demanding environments.

Unique features
THERMISTOR SENSING
Thermistor sensing offers a durable and reliable solution for condensate detection, eliminating common issues associated with traditional float switches, such as clogging and sticking. This technology monitors the temperature inside the tank, and when condensate comes into contact with the sensor, the Multitank detects the change and signals the pump to activate. Unlike float switches, thermistor sensing ensures consistent performance and accuracy, making it an ideal choice for systems that require precise and dependable condensate removal.
MULTIPLE DRAINAGE LINES
Specifically engineered to handle up to six condensate drainage lines, the Multitank is the ideal solution for spaces with multiple AC units totalling up to 50 kW. Designed with efficiency and versatility in mind, the Multitank supports up to six condensate lines using a single pump—offering a highly cost–effective and space–saving alternative. Its compact 1.5-litre (0.4 Gallon) tank activates the pump only when needed, helping to minimise energy consumption. This makes it an excellent choice for smaller installations where both performance and efficiency are critical.
COMPATIBLE WITH THE MAXIBLUE & MEGABLUE
The Multitank is compatible with our most powerful pumps; the MaxiBlue and MegaBlue. Despite their strength, both pumps operate quietly MaxiBlue (21 dB(A) and MegaBlue at 23 dB(A), ensuring minimal disruption. Both pumps are built with our exclusively patented Rotary Diaphragm Technology, featuring run-dry protection and self-priming capabilities for reliable, long-lasting performance.
