We investigate coherent-elastic neutrino-nucleus scattering (CEνNS) in 3-3-1 models for different values of β in which β is a parameter used to define the charge operator of the 331 models. We show that the number of events predicted by 331β model is in agreement with the data given by COHERENT experiment. We evaluate the sensitivity of the mass of Z' boson with 90% confidence level (CL) and find that mZ′≥1.4TeV for β=−3 with 90% CL. We perform χ2 fit for liquid Argon, Germanium and NaI detector subsystems, we obtain mZ′≥[2,3.1] TeV with 90\% CL. Our results indicate low-energy high-intensity measurements can provide a valuable probe, complementary to high energy collider searches at LHC and electroweak precision measurements.
