About Aspen Pumps

Aspen Pumps is a manufacturer of condensate removal pumps and related accessories for air conditioning and refrigeration systems. The company, headquartered in the United Kingdom, has established a product line that addresses the need for reliable condensate management in HVAC installations where gravity drainage is not feasible or practical. The product portfolio includes the Microblue, Miniblue, Maxiblue, and Megablue series, each engineered to meet specific flow, head, and installation requirements. These pumps are designed for use in commercial, industrial, and residential HVAC systems, providing a means to remove condensate from air handling units, fan coils, and refrigeration equipment without requiring a floor drain or sump pit.

The Microblue series is the most compact, delivering up to 5 liters per hour (1.3 gallons per hour) with a maximum head of 16 feet (approximately 5 meters). It operates at a noise level of 17 dBA, making it suitable for noise-sensitive environments such as offices, hotels, and residential spaces. The Microblue is available in configurations with an alarm tank, with or without shutoff, and supports a maximum suction lift of 2 meters and discharge distance of 5 meters. The Miniblue series offers a higher flow rate of 8 liters per hour, with a maximum suction distance of 5 meters and discharge distance of 8 meters, operating at 21 dBA. Miniblue models include continuous plug, probe reservoir, and temperature sensor variants, all utilizing rotary diaphragm pump technology and capable of dry-running. The Maxiblue series increases capacity to 14 liters per hour, with suction and discharge distances up to 8 meters each, also at 21 dBA. Maxiblue variants include the Drainstik alarm and shutoff, and the Pro alarm and shutdown, which come with a 3-year warranty. The Megablue series is the highest-capacity line, delivering 50 liters per hour with a maximum suction distance of 7 meters and discharge distance of 20 meters, operating at 23 dBA. The Megablue includes a reservoir alarm and shutoff feature, making it suitable for larger HVAC systems or applications with higher condensate production.

All Aspen Pumps units employ thermistor-level sensing or probe-based detection to monitor condensate levels and trigger pump operation or cutoff, ensuring automatic operation and preventing overflow. The pumps are available in dual-voltage configurations to accommodate different electrical infrastructures across global markets. The construction of these pumps emphasizes durability and quiet operation, with noise levels ranging from 17 to 23 dBA across the series. The rotary diaphragm technology used in Miniblue and Maxiblue models allows for dry-running capability, which reduces the risk of damage if the water supply is interrupted. The pumps are designed for easy installation, with compact footprints and multiple mounting options. 3G Electric supplies the full range of Aspen Pumps condensate removal pumps, ensuring that plant engineers, maintenance managers, and procurement specialists have access to these products for their HVAC and refrigeration projects. The availability of various models with different flow rates, sensing mechanisms, and alarm configurations allows for precise matching to system requirements, whether for a small split system or a large commercial air handling unit.

Frequently asked questions

Common questions about Aspen Pumps from 3G Electric.

What is the maximum head and flow rate of the Aspen Pumps Microblue series?

The Aspen Pumps Microblue series delivers a maximum flow rate of 5 liters per hour (1.3 gallons per hour) and can pump condensate to a maximum head of 16 feet (approximately 5 meters). This makes it suitable for applications where the condensate needs to be lifted to a higher discharge point, such as in ceiling voids or when routing drainage to a remote location. The Microblue operates at a low noise level of 17 dBA, which is beneficial in noise-sensitive environments. It is available in configurations with an alarm tank, with or without shutoff, providing options for systems that require overflow protection.

Can the Aspen Pumps Miniblue series operate without water (dry-running)?

Yes, the Aspen Pumps Miniblue series is designed with rotary diaphragm pump technology that allows for dry-running capability. This means the pump can operate without water for short periods without sustaining damage, which is useful during installation, maintenance, or if the condensate supply is intermittent. The Miniblue series delivers 8 liters per hour and operates at 21 dBA. It supports a maximum suction distance of 5 meters and a discharge distance of 8 meters. This dry-running feature enhances reliability and reduces the risk of pump failure in applications where water levels may fluctuate.

What is the difference between the Aspen Pumps Maxiblue Drainstik and the Maxiblue Pro?

The Aspen Pumps Maxiblue Drainstik and Maxiblue Pro are both rotary diaphragm condensate pumps with a flow rate of 14 liters per hour and a noise level of 21 dBA. The primary difference lies in their alarm and shutoff configurations. The Drainstik model (X87-702) includes an integrated alarm and shutoff mechanism, which alerts users to high water levels and automatically shuts off the pump to prevent overflow. The Maxiblue Pro (X87-707) also provides alarm and shutdown functionality but comes with a 3-year warranty, indicating a higher level of durability and long-term reliability. Both models handle suction and discharge distances up to 8 meters, making them suitable for a range of HVAC installations.

What is the maximum suction and discharge distance for the Aspen Pumps Megablue series?

The Aspen Pumps Megablue series is designed for high-capacity condensate removal, delivering 50 liters per hour. It supports a maximum suction distance of 7 meters and a maximum discharge distance of 20 meters, allowing for installation in systems where the condensate source is located far from the discharge point. The Megablue operates at a noise level of 23 dBA, which is slightly higher than other series but still relatively quiet. It includes a reservoir alarm and shutoff feature (X87-813) to provide overflow protection. This series is suitable for larger air conditioning systems or applications with high condensate production, such as commercial buildings or industrial facilities.

How does the sensing technology in Aspen Pumps condensate pumps work?

Aspen Pumps condensate pumps use either thermistor-level sensing or probe-based detection to monitor condensate levels. Thermistor sensors detect changes in temperature caused by the presence of water, triggering the pump to activate when the water level rises and deactivate when it drops. Probe-based systems use electrical conductivity to sense water level, with probes placed at specific heights in the reservoir. When the water reaches the probe, the pump turns on; when it falls below, the pump turns off. These sensing methods ensure automatic operation without the need for float switches, which can be prone to mechanical failure. The choice of sensing technology varies by model, with some series offering both options to suit different installation preferences.

Are Aspen Pumps available in dual-voltage configurations for international use?

Yes, Aspen Pumps condensate pumps are available in dual-voltage configurations to accommodate different electrical infrastructures in various geographic markets. This means the pumps can operate on both 110-120V and 220-240V power supplies, making them suitable for use in countries with different voltage standards. This feature is particularly important for global projects where equipment may be sourced from one region and installed in another. When selecting a pump, it is essential to verify the voltage rating of the specific model to ensure compatibility with the local power supply. 3G Electric can provide guidance on the appropriate voltage configuration for your application.
