Peristaltic Condensate Pumps target US mini-split market.

Press Release Summary:

Intended for mini-split air conditioners, Purple Series keeps condensate contained inside transparent, flexible vinyl tubing to isolate it from pumping mechanism. Pumps can run wet or dry, eliminating need for filters, and degree of suction enables remote mounting of up to 40 ft from evaporator. Products suit applications requiring quietness (47 dB max) of remote operation or compromised environments such as foodservice or industrial areas. Mechanical and Universal kits are available.

Airtec Introduces Peristaltic Condensate Pumps for U.S. Minisplit Market

Peristaltic pumps are perfect solutions for minisplit condensate control in quiet or harsh industrial and foodservice environments.

Airtec Products Corp., Fall River, Mass., a leading manufacturer and importer of HVAC/R products, introduces Aspen Pumps' Purple Series of peristaltic condensate pump kits for minisplit air conditioners. Peristaltic pumps are ideal in applications requiring the quietness of remote operation or in compromised environments such as foodservice or industrial areas where excess dirt or oil create blockages in conventional minisplit condensate pumps.

Unlike other pump methods, the condensate is contained inside transparent, flexible vinyl tubing, which isolates it from the pumping mechanism. The process of peristalsis rotationally compresses the tubing causing the condensate to move through it. Therefore, the Purple Series pumps can run wet or dry, don't need filters that can potentially restrict flow when not periodically maintained, and are ideal choices when dust, oils or other heavy pollutants contaminate the condensate on a minisplit evaporator's coil or in the drain pan. The Purple Series' high suction enables remote mounting of up to 40 feet from the evaporator, making it a good choice for noise sensitive environments such as bedrooms, nursing home rooms, recording/broadcast studios, or live performance areas.

The Purple Series offers both Mechanical and Universal kits, which use different switching methods, but are both located remotely of the minisplit. They pump1.65-gph to a maximum head of 33 feet and require either 115-V or 230-V power. The (h)5-1/2 x (w)3-3/8 x (d)7-inch Mechanical Pump kit uses a separate reservoir for mounting inside the minisplit with an internal float mechanism and electronic switch, which activates the pump and can also disable the system during an overflow incident. The smaller (h)4-1/2 x (w)3 x (d)5-1/2-inch Universal Pump and kit has the same features, but uses a temperature differential sensor switch, which can be attached to the lineset to control pump operation.

The Purple Series features these quick installation and easy maintenance designs:
  • Pump is easily removed for maintenance by pulling out power plug without disconnecting power wiring.
  • Disengages easily from quick-install wall bracket housing.
  • Pump head is easily replaced after 10,000-hour duty cycle (approximately two years).
  • No filters to change.
  • Internal fuse eliminates searching for external fuses.

    Other features include:
  • Quiet operation at maximum 47-decibels.
  • Remote placement up to 10 feet vertically and 40 feet horizontally.

    Aspen Pumps, a world leader in condensate pumps for minisplit a/c, offers a wide selection of configuration and installation flexibility through the Orange, Aqua, Lime and White Series to accommodate any minisplit brand or model. All four series are designed to run wet, therefore they all include a reservoir, which has a filter to clean periodically and a float switch, which prevents dry operation and disables the unit in an overflow situation.
  • Orange Series-includes the Mini (26-foot-pumping-head) or Maxi (65-foot-pumping head) and installs inside the evaporator-when space permits, along the lineset path or above the ceiling.
  • Aqua Series-ultra-slim profile (26-foot-pumping head) fits inside most minisplit models, or it can be installed along the lineset path or above the ceiling.
  • Lime Series-the reversible pump is contained in a 90-degree surface-mounted lineset duct elbow. Both the Mini (26-foot-pumping-head) and Maxi (49-feet-pumping-head) kits include a 31-inch lineset duct and fittings to hide any lineset running down an inside wall.
  • White Series-a monobloc pump assembly (33-foot-pumping-head) designed for surface installation underneath the minisplit evaporator unit for superior aesthetics and ease of maintenance.
