The X-Series of modular makeup air units includes the Model MSX, a new modular supply unit that is ideal for makeup air applications where gas-fired heating is not desired, the company says. Larger housing sizes, capacity to 15,000 cfm, greater mechanical and evaporative cooling capacities, and added mixing box capabilities are some of the features and benefits of the unit, states the company. Coil heating and/or cooling tempering options are available, or the unit can be used for untempered applications.
