This XeteX project highlights one of two custom RTUs for a hospital. Equipped with packaged DX refrigeration, a post hot water coil, and quality filtration throughout, this custom RTU is designed for energy efficient, year-round temperature regulation and indoor air quality. Designed as a replacement, the unit was painted a custom color to match nearby equipment.
