The company’s newest rooftop unit - the AC-410 - is designed for use on small school buses. The AC-310 has a cooling capacity of 83,000 BTU/hour, while the AC-350 has a cooling capacity of 96,000 BTU/hour. “People are asking for them to avoid bringing heat and dust from the road into their buses.”Ĭarrier Transport Air Conditioning manufactures several roof-mount systems for school buses.
“We’re also developing and testing rooftop condensers,” Lucas says. This unit has a heat-rejecting capacity of 78,000 BTU/hour, which results in a lower cooling temperature and lower head pressure, while its 12-inch fan increases airflow. It can be installed in the front or rear of a bus however, it is also specially designed to be installed in areas where space is limited.ĪCT offers skirt-mount condensers for school buses, including the CS-3. The EV-10 has a cooling capacity of 30,000 BTU/hour and comprises many of the same features as the EZ-2. The EZ-2 also features pressure switches to ensure compressor protection, and its rifled copper tubing coils increase system performance. It can be flush-mounted at the front or rear of a bus and its louver design enhances airflow throughout the vehicle. This unit has a cooling capacity of 50,000 BTU/hour. Within the EZ series, Lucas says the EZ-2 is a popular model.

Two series of in-wall evaporators are available: the EZ and EV (evaporator vertical) series. Lucas, American Cooling Technology (ACT) specializes in “split” air conditioning systems, where the evaporator is installed inside the bus and the condenser is installed under the bus.ĪCT offers ceiling-mount evaporators and in-wall evaporators. The company also uses ground-leg switching, which decreases the number of hot wires running through a system and which Hamilton believes makes ACC’s products safer compared to companies that use multiple wires to power their units.Īccording to Vice President J.R. “An orifice tube is not, and with an accompanying accumulator, more oil will be sent back to the compressor and increase its lifespan.”
“Expansion valves are a high-failure item in most air conditioning systems,” Hamilton explains. Hamilton says ACC Climate Control strives to “think outside of the box” when developing its products - the company uses an orifice tube accumulator design system rather than dryers with expansion valves. The unit has a heat-rejecting capacity of 78,000 BTU/hour and can generally be installed without cutting large holes in a bus’ skirt. The condenser’s counter-flow coil circuitry and the crosshatching within its tubing walls improve heat rejection and sub-cooling.
The evaporator has a cooling capacity of 53,000 BTU/hour and features an orifice tube that is used in conjunction with an enhanced copper tube and an aluminum fin coil to enhance the unit’s durability and maximize BTU output. Scott Hamilton, part of the company’s sales team, says the most commonly installed evaporator/condenser combination is a dual set of its 23023 Series Evaporator Twin Blower and its 25031 Series Condenser. The following outlines system specifications and new developments from seven air conditioning manufacturers, many of which also provide maintenance and installation services to end users.ĪCC Climate Control offers numerous air conditioning components for school buses.
